Question

Sabrina bought 90g of chocolate and 32hg of peanut butter for each of her 4 classmates. How many centigrams total did she buy?

Answer 1

We need to use conversions and ratios.

1 g = 100 cg

90 g= 90(100 cg)= 9,000 cg

1 hg= 100 g= 100(100 cgs)= 10,000 cg

32 hg= 32(10,000 cg)= 32,000 cg

9,000 cg+32,000 cg= 41,000 cg

41,000 is the amount for each of her 4 classmates.

41,000* 4= 164,000

Sabrina bought 164,000 cg total of chocolate and peanut butter.
