Answer:
1/4 x 5 = 5/4 = 1 1/4
1 1/2 x 2 1/5 = 33/10 = 3 3/10
2/9 ÷ 1/3 = 2/3
5 ÷ 2/3 = 15/2 = 7 1/2
Step-by-step explanation:
1/4 x 5
1/4 x 5/1 = 5/4
----------------------
1 1/2 x 2 1/5
1 1/2 = 3/2
2 1/5 = 11/5
3/2 x 11/5 =33/10 = 3 3/10
-------------------------------------
2/9 ÷ 1/3
KCF:
2/9 x 3/1 = 2/3 x 1/1 = 2/3
----------------------------------------
5 ÷ 2/3
5/1 ÷ 2/3
KCF:
5/1 x 3/2 = 15/2 = 7 1/2
-----------------------------------------------
KCF ( keep change flip ): This is a way of solving division with fractions by keeping the first fraction the same, changing the division to multiplication, and flipping the other fraction.
