Problem Of The Week
I would rather have 75% of 80¢
because 10% of 5$ is 50¢ and 75% of
80¢ is 60¢.
Working out:
50%of $5= $2.5
$2.5 divided by 5 = $0.5.
$0.5 x 100 = 0.50¢
50%of 80¢= 40¢,
25% of 80¢=20¢,
50%+25%=75%,
40¢+20¢=60¢
I would rather have 26% of 5
pizzas because 60%of 2 pizzas is 1.2 pizzas and 26% of 5 pizzas is 1.3 pizzas.
Working out: 60%divided by 100= 0.60
0.60 x 2= 1.2 pizzas
26% divided by 100=0.26
0.26 x 5=1.3 pizzas
I would rather be bitten by 15%of 120
mosquitoes because it is 18 bites and
8% of 250 mosquitoes is 20 bites.
Working out:
15% divided by 100=0.15
0.15 x 120=18 bites
8% divided by 100= 0.8
0.8 x 250=20 bites
I would rather skip with a rope
that is 88%of 275 in. long.
Working Out: 54% divided by 100=0.54
0.54 x 105=56.7 in.
88%divided by 100=0.88
0.88 x 275= 242 in.

I would rather sit in a traffic jam for
33%of 2 hours because it is 40.20
minutes and 44%of 1hr 40mins is
44.00.
Working Out:
33% divided by 100= 0.33
0.33 x 120 minutes =40.20 mins
44% divided by 100= 0.44
0.44= 44 minutes
