Question

Simply -15+(-3.7+9.15 /5)•32-4.7

Answer 1

-79.54

Explanation:

= -15+(-3.7+9.15/5)*32-4.7

= -15+(-3.7+1.83)*32- 4.7

= -15(-1.87)*32- 4.7

= -15 - 59.84 - 4.7

= -79.54

Answer 2

-79.54

Explanation:

To answer this question we have to use BIDMAS (brackets, indices, division, multiplication, addition and subtraction).

1) This means that we first have to do the brackets! We have to be careful to do the division inside the brackets first.

• 9.15 ÷ 5 = 1.83
• -3.7 + 1.83 = -1.87

This leaves us with -15 -1.87 × 32 - 4.7

2) We next have to do the multiplication!

• -1.87 × 32 = -59.84

Leaving us with -15 - 59.84 - 4.7

3) Now we can just do the subtraction!

• -79.54

Hope this helps, have a lovely day! :)
