What factor makes the number sentence true 7×4 = ?×7

Answers

Answer 1

Answer: The answer is 4. According to the commutative property, you can commutate (swap) numbers over and get the same result. However, it only works for addition and multiplication. For instance, x + y = y + x. Or, x * y = y * x. In our example, we have 7 * 4 = ? * 7. Because we already have 7 on the right side of the expression, the missing number will be 4.

Write an expression that can be used to multiply 6 x 198 mentally? please answer thanks!

Answers

-6 x 2 + 6 x 200. Since you want to find out 6 multiplied by 198 the easiest way (for me) would be to round it and then substract 12 since 200-198 is equal to 2 and 6 x 2 is equal to 12

Assuming you meant 6 x 198... Do a mental sum for 6 x 200 (1200) then subtract 6
