Question

This will be worth ten points

Answer 1

First, you can write that 1260 ÷ 15 = 84.

To prove this one way, you can show the multiplication of the quotient and divisor.  If the division was correct, it would end up as the value of the dividend:

84 * 15 = 1260
1260 = 1260

To prove this another way, you can show 84 being added 15 times and seeing if it totals 1260:

84 + 84 + 84 + 84 + 84 + 84 + 84 + 84 + 84 + 84 + 84 + 84 + 84 + 84 + 84 = 1260
1260 = 1260

Answer 2

Answer:

1260/15=84

Step-by-step explanation:

1200/15=80 and 60/15=4

80 + 4 = 84.

Another way is 15 + 15 + 15 and keep counting 84 times and you would get 84
