Question

A piece of cable 8.5 cm long weighs 52 grams. How much does a cable that is 10 cm long weigh

Answer 1

8.5 cm cable weighs = 52 grams

1 cm of cable weighs =
`(52)/(8.5)grams`

=
`52/ (85)/(10)` grams
=
`52* (10)/(85)` grams
=
`(520)/(85)` grams
=
`6.11764` grams
Rounding it up = 6. 10000 grams

Then,

10 cm of cable weighs =
`6.10*10` grams
=
`61.0` grams
