Question

use distributive property
to solve 3 / 5 * - 7 / 8 + 9/ 15 * 7 by 8​

Answer 1

Hey Dear,

◆ Answer -

3/5 × -7/8 + 9/15 × 7/8 = 0

● Explanation -

Let's take this step-by-step -

3/5 × -7/8 + 9/15 × 7/8 = -3/5 × 7/8 + 9/15 × 7/8

Using distributive property,

3/5 × -7/8 + 9/15 × 7/8 = 7/8 (-3/5 + 9/15)

But we know, 9/15 = 3×3/5×3 = 3/5,

3/5 × -7/8 + 9/15 × 7/8 = 7/8 (-3/5 + 3/5)

3/5 × -7/8 + 9/15 × 7/8 = 7/8 × 0

3/5 × -7/8 + 9/15 × 7/8 = 0

Therefore,

3/5 × -7/8 + 9/15 × 7/8 = 0

Hope this helped...

Answer 2

Step-by-step explanation:

3/5×-7/8+9/15×7/8=7/8(-3/5+9/15

3/5×-7/8+9/15×7/8=7/8(-3/5+3/5)

3/5×-7/8+9/15×7/8=7/8×0

3/5×-7/8+9/15×7/8=0
