Question

Li is using an array to solve the divison problem 294÷7. She first subtracted 40 rows of 7. How many more rows of 7 can Li make in the array?

Answer 1

Li can make two more rows of 7 in the array

Here, we want to know the number of remaining rows of 7 to be subtracted

From the question, we are told that she first made a subtraction of 40 rows of 7

Mathematically, that will be a value of;

$40\times7\text{ = 280}$

The number subtracted is 280

The number left is thus;

$294-280\text{ = 14}$

To get the remaining rows of 7, we simply proceed to divide 14 by 7

We have this as 14/7 = 2

That means 2 more rows of 7 can be made in the array
