5.55 divide by 4
5.55 divide by 4
x= 1.5 4x -2=4 <<< Original problem +2 +2 <<< reverse operations (problem requires subtraction, so add to solve) 4x=6 <<< New problem 4x/4=6/4 <<<reverse operations (new problem requires multiplication, so divide to solve) x=1.5 <<< answer
You can divide 16 by 4 to get you 4
1200. Reverse the operation: reverse of divide is multiply, thus 60 x 20 = 1200
Divide by 4.
72 reverse the digits divide by 3 = 24
The reverse, in the sense of undoing the effects of "divide by 21" is "multiply by 21".
divide by 21
Divide by 622.
Divide by 9
Multiply by 36
multiply by 1/38
4. Reverse the process to find the number: 7 is added to the product of 3 and a number to get 19. The last thing done is add 7; the reverse process of add is subtract, so subtract 7, leaving: The product of 3 and a number is 19 - 7 = 12. The reverse process to multiply (product) by 3 is divide, so divide by 3, leaving: a number is 12 ÷ 3 = 4
