Answer:
- dividend: 2; divisor: 2/5
- groups of: 2/5
- 5 groups
Step-by-step explanation:
dividend ÷ divisor = quotient . . . . . names of parts of a division expression
In the expression A ÷ B, the dividend is A and the divisor is B.
__
The multiplication fact A·B = C gives rise to two division facts:
A = C/B
B = C/A
So, the multiplication fact (2/5)·5 = 2 gives rise to the two division facts:
(2/5) = 2/5
5 = 2/(2/5) . . . . . . . this is the one this problem is trying to illustrate
The slash and the "divided by" symbol mean the same thing, so this can also be written as ...
5 = 2 ÷ 2/5
or
2 ÷ 2/5 = 5 . . . . 2 is the dividend; 2/5 is the divisor
__
To see how many times 2/5 goes into 2, we can draw the given diagram and see how many groups of 2/5 we can make out of the equivalent fractions. We find there are 5 such groups. This means "2/5 goes into 2 five times" or "2 divided by 2/5 is 5."
