Question

9/8÷3/5of(3/4+3/5)simplif answer

Answer 1

answer is 81/32
because when we simplify it first we simplify bracket 3/4 +3/5 the lcm is 20after solving it we get 27/20 after we divide 9/8 ÷ 3/5
9/8 × 5/3 we get 15/8 and then solve of 27/20× 15/8 = 81/32

Answer 2

Answer:

$\frac{\frac{9}{8}}{\frac{3}{5}} \text{ of }(\frac{3}{4}+\frac{3}{5})=2.53125$

Step-by-step explanation:

Given : Expression  $\frac{\frac{9}{8}}{\frac{3}{5}} \text{ of }(\frac{3}{4}+\frac{3}{5})$

To find : Simplify the expression?

Solution :

Expression  $\frac{\frac{9}{8}}{\frac{3}{5}} \text{ of }(\frac{3}{4}+\frac{3}{5})$

Solve into parts,

1) $\frac{\frac{9}{8}}{\frac{3}{5}}=\frac{9}{8}\times \frac{5}{3}$

$\frac{\frac{9}{8}}{\frac{3}{5}}=\frac{3\times 5}{8}$

$\frac{\frac{9}{8}}{\frac{3}{5}}=\frac{15}{8}$

2) $\frac{3}{4}+\frac{3}{5}=\frac{15+12}{20}$

$\frac{3}{4}+\frac{3}{5}=\frac{27}{20}$

Substitute back in the form,

$=\frac{15}{8} \text{ of }(\frac{27}{20})$

$=\frac{15}{8}\times\frac{27}{20}$

$=\frac{3\times 27}{8\times 4}$

$=\frac{81}{32}$

$=2.53125$

Therefore, $\frac{\frac{9}{8}}{\frac{3}{5}} \text{ of }(\frac{3}{4}+\frac{3}{5})=2.53125$
