Each gold coin is 5 mm thick, and each silver coin is 2 mm thick. A stack of 148 gold coins and 216 silver coins is about ___________ cm thick.

Height of gold coin = 5 mm
Silver coin height = 2 mm
Height of 148 gold and 216 silver coins = 148 x 5 mm + 216 x 2 mm = 740 + 432 mm = 1172 mm = 1172/10 cm = 117.2 cm ( 1 cm = 10 mm)

John is 15 years old. His father is 45 years 9 months old. Find the difference between their ages.

Brenda is 12 years 6 months old and Patty is 12 years 8 months old. Their total age is _________.

Brenda = 12 years 6 months
Patty = 12 years 8 months
Total age = 12 yr 6 mnth + 12 yr 8 mnth= 24 years 14 months.
12 months = 1 year.
14 months = 1 years 2 months.
Total age= 25 years 2 months.

Jack is an athlete. During his daily training, Jack hops along a path that is 35 yards long. If he can hop forward 15 inches each time, ________hops he can make along the path.

Ashley's teacher asked her to bring 3 pieces of yarn, each no shorter than 0.8 m, for an art project. Ashley found a piece of old yarn at home that is 280 cm long. Does she have enough yarn to bring to school?

230 erasers = 230 x 17 mm =3910 mm = 3.910 m ( 1 m = 1000 mm)

Difference in time from 7 : 15 pm to 10 : 45 pm = 3 hr 30 mins.=3:30
Length of 1 yarn = 0.8 m
Length of 3 yarns = 3 x 0.8 = 2.4 m= 240 cm ( 1 m = 100 cm)
Ashley has 280 cm of yarn, which is more than 240 cm . hence, she does have enough yarn to bring to school.
