The reciprocal of a number (also called the multiplicative inverse) means 1/this number or (This number)^-1
So, to get the reciprocal of 7/2a, you need to divide 1 by this number as follows:
reciprocal = 1 / (7/2a) = 2a/7
The answer is : 2a/7
Write an Expression:
4.25*9 = X
4.25*9 = 38.25 in²
4i/(1+i) + (6+3i)
multiply the first fraction by the conjugate
2i + 6+3i = 6+5i
6+5i
Simple explanation:
Divide 360 by 40
360/40 = 9
Cody needs 9 wrappers.
3rd grader explanation:
Explain that Cody wants to divide 360 into __ groups of 40.
Use an illustration of separating things into equal groups (you can simply use separating 6 objects into equal groups of 2).
Explain that subtraction, multiplication, or addition will not help.
Tell him/her to use division.
Although 360 and 40 are large numbers, explain that the 0's can be removed into 4 and 36.
36 / 4 = 9
Since the answer is 9, Cody needs 9 wrappers.
Have an awesome day! :)
