Question 1.
At a party, there are 8 guests. Each guest eats 2$$\frac{1}{4}$$ oranges.
How many oranges do the 8 guests eat?

Question 3.
Nolan practices the piano for 1$$\frac{2}{5}$$ hours every Saturday and Sunday. How long does he practice each weekend? Express your answer in hours and minutes.
he practiced 2 hours 48 minutes
Explanation:
1$$\frac{2}{5}$$ hours on Saturday
1$$\frac{2}{5}$$ hours on Sunday
1$$\frac{2}{5}$$ + 1$$\frac{2}{5}$$
2$$\frac{4}{5}$$
1 hour = 60 minutes
5 parts of 60 = 5 x 12 = 60
60 – 12 = 48
so, he practiced 2 hours 48 minutes

5 x 10$$\frac{1}{2}$$
= 50$$\frac{5}{2}$$
= 52$$\frac{1}{2}$$
Angela earn in 7 weeks
7 x 52$$\frac{1}{2}$$

Explanation:
7 x 5 = 35
35 x 7 = 245
245 x 1$$\frac{1}{2}$$
367$$\frac{1}{2}$$
