Question

Grant finds the difference of 360 and 127 as shown. What is Grant's

Answer 1

Answer:

D. Grant did not regroup the 4 tens when he  subtracted 7.

Step-by-step explanation:

In the process of subtraction, regrouping is important so that each digit in the given numbers are placed appropriately before the required arithmetic operation is performed.

The correct step to Grant's solution are:

360 - 100 = 260

260 - 20 = 240

240 - 7 = 233

Grant's final answer ought to have been 233.

Going through his solution, he made a mistake while subtracting 7 from 240. He failed to regroup the 4 tens when he  subtracted 7 from 240. Thus the essence of his wrong answer.
