Answer:

Divide: 5/ 18 : 2/ 3  = 5/ 18  · 3/ 2  = 5 · 3/ 18 · 2  = 15/ 36  = 3 · 5/ 3 · 12  = 5/ 12  

Dividing two fractions is the same as multiplying the first fraction by the reciprocal value of the second fraction. The first sub-step is to find the reciprocal (reverse the numerator and denominator, reciprocal of 2/ 3  is 3/ 2 ) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators. In the next intermediate step, , cancel by a common factor of 3 gives 5/ 12 .

In words - five eighteenths divided by two thirds = five twelfths.

Multiple: 1/ 2  * 3/ 5  = 1 · 3/ 2 · 5 = 3/ 10

Multiply both numerators and denominators. Result fraction keep to lowest possible denominator GCD(3, 10) = 1. In the next intermediate step, the fraction result cannot be further simplified by canceling.

In words - one half multiplied by three fifths = three tenths.

Subtract: the result of step No. 1 - the result of step No. 2 = 5/ 12  - 3/ 10  = 5· 5/ 12 · 5  - 3 · 6/ 10 · 6  = 25/ 60  - 18/ 60  = 25 - 18/ 60  = 7/ 60

For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of both denominators - LCM(12, 10) = 60. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 12 × 10 = 120. In the next intermediate step, the fraction result cannot be further simplified by canceling.

In words - five twelfths minus three tenths = seven sixtieths.

Add: 3/ 5  + the result of step No. 3 = 3/

5  + 7/ 60  = 3 · 12/ 5 · 12  + 7/ 60  = 36/ 60  + 7/ 60  = 36 + 7/ 60  = 43/ 60

For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of both denominators - LCM(5, 60) = 60. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 5 × 60 = 300. In the next intermediate step, the fraction result cannot be further simplified by canceling.

In words - three fifths plus seven sixtieths = forty-three sixtieths.

Subtract: 3 - the result of step No. 4 = 3 - 43/ 60  = 3/ 1 - 43/ 60  = 3 · 60/ 1 · 60  - 43/ 60  = 180/ 60  - 43/ 60  = 180 - 43/ 60  = 137/ 60  

For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of both denominators - LCM(1, 60) = 60. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 1 × 60 = 60. In the next intermediate step, the fraction result cannot be further simplified by canceling.

In words - three minus forty-three sixtieths = one hundred thirty-seven sixtieths.

Conversion a mixed number 6 3/ 7

to a improper fraction: 6 3/7 = 6 3/ 7  = 6 · 7 + 3/ 7  = 42 + 3/ 7  = 45/ 7  

To find new numerator:

a) Multiply the whole number 6 by the denominator 7. Whole number 6 equally 6 * 7/ 7  = 42/ 7  

b) Add the answer from previous step 42 to the numerator 3. New numerator is 42 + 3 = 45

c) Write a previous answer (new numerator 45) over the denominator 7.

Six and three sevenths is forty-five sevenths Multiple: 45/ 7  * the result of step No. 5 = 45/ 7  * 137/ 60  = 45 · 137/ 7 · 60  = 6165/ 420  = 411 · 15/ 28 · 15  = 411/ 28

Multiply both numerators and denominators. Result fraction keep to lowest possible denominator GCD(6165, 420) = 15. In the next intermediate step, , cancel by a common factor of 15 gives 411/

28  

In words - forty-five sevenths multiplied by one hundred thirty-seven sixtieths = four hundred eleven twenty-eighths.
