Question

find the sum of 7 /8 ,5 / 6 and 3 /4​

Answer 1

Answer:

this is the answer.....

Answer 2

Answer:

The sum of the mentioned fractions is $\frac{59}{24}$ or 2.45

Explanation:

The question can be solved in two methods:

Method:1

Fractions given = $\frac{7}{8} ,\frac{5}{6} ,\frac{3}{4}$

Taking LCM.

8-6-4 = 2*2*2 - 3*2 - 2*2

Thus, LCM = 2*2*2*3 = 24

Converting Fractions,

$\frac{7}{8}*\frac{3}{3} = \frac{21}{24}$

$\frac{5}{6}*\frac{4}{4} = \frac{20}{24}$

$\frac{3}{4}*\frac{6}{6} = \frac{18}{24}$

Adding all the fractions,$\frac{21+20+18}{24} = \frac{59}{24}$

Method:2

Converting fractions in decimal numbers,

$\frac{7}{8} = 0.875$

$\frac{5}{6} = 0.834$

$\frac{3}{4} = 0.750$

Adding all the values,

0.875+0.834+0.750= 2.45

Definition:

LCM:

• The acronym LCM means least common multiple.
• When you multiply a number with or by a whole number, you obtain a multiple (greater than 0).
• A factor is a number produced when a whole number is multiplied by another.

Fraction:

• Any number of equal parts is represented by a fraction, which also means a portion of a whole.
• A fraction, such as one-half, eight-fifths, or three-quarters, indicates how many components of a particular size are when stated in ordinary English.
