If 9 pairs of space boots cost $6,750, then 1 pair costs
If 9 pairs of space boots cost $6,750, then 1 pair costs
The correct option is A $750
Cost of 9 pairs of space boots = $6,750
∴ Cost of 1 space boot = $6,750÷9
Step 1:
The 6 in the thousands place of 6,750 is smaller than 9. So, we write 0 on the top and subtract 0 from 6 to get 6.
Step 2:
Bringing down the 7 in the next place, we get 67.
63 is the 7th multiple of 9, and just a little less than 67.
So, we write 7 at the top and subtract 63 from 67, which gives 4 as the difference.
Step 3:
We take the number 5 to right of 4 to make it 45.
45 is the 5th multiple of 9. So, we write 5 at the top and subtract 45 from 45 to get 0.
Step 4:
Bringing down the last digit on the right, we get 0. And as 9 × 0 = 0, we write 0 on the top and remainder is 0.
So, $6750 ÷ 9 = $750
∴ Cost of 1 space boot = $750
Cost of 9 pairs of space boots = $6,750
∴ Cost of 1 space boot = $6,750÷9
Step 1:
The 6 in the thousands place of 6,750 is smaller than 9. So, we write 0 on the top and subtract 0 from 6 to get 6.
Step 2:
Bringing down the 7 in the next place, we get 67.
63 is the 7th multiple of 9, and just a little less than 67.
So, we write 7 at the top and subtract 63 from 67, which gives 4 as the difference.
Step 3:
We take the number 5 to right of 4 to make it 45.
45 is the 5th multiple of 9. So, we write 5 at the top and subtract 45 from 45 to get 0.
Step 4:
Bringing down the last digit on the right, we get 0. And as 9 × 0 = 0, we write 0 on the top and remainder is 0.
So, $6750 ÷ 9 = $750
∴ Cost of 1 space boot = $750
