a. 1/ 15
b. 76/ 15
c. 1/12
a. 2/5 divided by 6
= 2/ 5 ÷ 6
= 2/ 5 ÷ 6/ 1
Take the inverse of the dividing fraction, we have
= 2/ 5 × 1/ 6
Multiply through
= 2/30
= 1/ 15
b. 3 and 1/3 times 5 and 2/5
= 3 + 1/ 3 × 5 + 2/ 5
From the knowledge of BODMAS, we multiply first
= 3 + 5/3 + 2/ 5
Find the LCM
= 45 + 25 + 6/ 15
= 76/15
c. 1/4 + 1/3 -1/2
Let's find the LCM
= 3 + 4 - 6 / 12
Add first
= 7 - 6/ 12
= 1/ 12
