Answers
Step-by-step explanation:
firstly change into improper fraction then change the of into multiply and then solve
Concept:
A fraction or a whole number is produced when one fraction is multiplied by another fraction. The numerator and denominator of a fraction are well known to exist. As a result, the numerators and denominators of any two fractions are multiplied in turn. A fractional multiplication example is 23 x 14 = (2 x 1)/(3 x 4) = 2/12 = 16. The denominators of the two fractions do not need to match when multiplying fractions, unlike with adding or subtracting fractions. Even when the denominators are different, it is simple to multiply two fractions. It is important to keep in mind while multiplying fractions that they might be in either a proper or improper fraction but not a mixed fraction.
When dividing a fraction by another fraction, we reciprocally transform the second fraction before multiplying it by the first.
Example: 2/3 ÷3/4.
Solution: To get 4/3, change 3/4 into its reciprocal.
Now divide 2/3 by 4/3.
⇒2/3 x 4/3
⇒ (2×4)/(3×3)
⇒ 8/9.
Given:
3 2/5 ÷ 4/5 of 1/5 +2/3 of 3/4 -1 35/72
Find:
Simplfy 3 2/5 ÷ 4/5 of 1/5 +2/3 of 3/4 -1 35/72
Solution:
3 2/5 ÷ 4/5 of 1/5 +2/3 of 3/4 -1 35/72
17/5÷ 4/5 of 1/5 +2/3 of 3/4 - 107/722
= 17/5 ÷4/5x 1/5 +2/3x3/4 -107/72
=17/5 x 5/4 x 1/5 +1/2 - 107/72
= 17/20 + 1/2 -107/72
=(17+10)/20 - 107/72
= 27/20 - 107/72
(18(27) - 5(107))/1360
=( 486-535)/360
= -49/360
Therefore, the answer is -49/360
