Question

verify that (5/2×-10/3)×9/4=5/2×(-10/3×9/4) pls answer step by step​

Answer 1

Step-by-step explanation:

Given verify the answer(-9/5×-10/3)×21/ 4=-9/5x(-10/3×21/-4)

Given (- 9/5 x - 10/3) x 21 / - 4 = - 9/5 x (-10/3 x 21 / - 4)

This expression is of the form associative property of multiplication. Now we need to verify both the expression are equal.

So (- 9/5 x - 10/3) x 21/-4

90/15 x 21 / - 4

So we get - 63/2

Now - 9/5 x (- 10/3 x 21 / - 4)

So 9/5 x 210 / -12

So we get - 63/2

Therefore I. h.s = r. h.s

Answer 2

Step-by-step explanation:

LHS= (5/2×-10/3)×9/4

> -25/3 × 9/4

>. -75/4

RHS= 5/2×(-10/3×9/4)

> 5/2× -30/4

> - 75/4

SO LHS= RHS
