Question

17.5*3-21+7-3*12.5 what is his evalute​

Answer 1

Answer:

By using the BODMAS rule

Step-by-step explanation:

17.5*3=52.5

3*12.5= 37.5

52.5-21=31.5

7-37.5=30.5

Therefore, 31.5=30.5=62

Answer 2

The value of (17.5 × 3 - 21 + 7 - 3 × 12.5) is "1".

Step-by-step explanation:

We have,

17.5 × 3 - 21 + 7 - 3 × 12.5

Using BODMAS rule,

= (17.5 × 3) - 21 + 7 - (3 × 12.5)

= 52.5 - 21 + 7 - 37.5

= (52.5 + 7)  - 21 - 37.5

= 59.5 - 58.5

= 1. 0

Hence, the value of (17.5 × 3 - 21 + 7 - 3 × 12.5) is 1.
