Before adding dissimilar fractions (fractions with different denominator), you have to make the fractions similar first. To make the fractions similar, find the Least Common Multiple of the denominator. In this case, the LCM is 10. Then rewrite the fractions using the LCM as the denominator.
9/10 = 9/10; 4/5 = 8/10
You can now proceed with addition -
9/10 + 8/10 = 17/10 or 1 7/10

joja [24]

Answer: Yes he does.

Step-by-step explanation:

The shirt costs £9.60 and is on discount by 1/3.

1/3 = 0.3333

The discounted price is therefore:

= 9.60 * (1 - 0.3333)

= £6.43

The price of two shirts is:

= 6.43 + 6.43

= £12.86

Billy has £13 which is above the price of two so he will be able to buy 2 shirts.
