Answer:
The decimal will move 1 place value to the left. For example 10 to the first power is 10 so 15.3/10 will equal to 1.53.
We know that each row would require 62 bricks, and considering that the wall will have multiple rows, we will be multiplying 62 by the number of rows. Since the wall has 10 rows, Nick has to use the 62 bricks 10 times (since 1 row requires 62 bricks, he would have to build that 1 row 10 times.)
If we think about the operation of multiplication, we can write “62 ten times” as 62 x 10 (or, when calculated, 620 bricks).
Larger number = X
Smaller number = 1/2X
X + 1/2X = 60
Simplify:
1 1/2x = 60
Divide both sides by 1 1/2:
x = 40
The numbers are 20 and 40
