Express 630 grams as a percentage of 1 kilogram

zubka84 [21]

63%

To express as a percentage divide 630 g by 1 Kg and multiply by 100%

note that 1 Kg = 1000 g ( units must be the same)

$\frac{630}{1000}$ × 100% = 63%

A turtle can walk 1/12 of a kilometer in an hour the turtle is 1/5 of a kilometer away from a pond

34kurt

Answer:

$2\frac{2}{5}\ h$

Step-by-step explanation:

we know that

A turtle can walk 1/12 of a kilometer in an hour

by proportion

Find how long will it take the turtle to reach the pond (1/5 km)

$\frac{1}{(1/12)}\frac{h}{km}=\frac{x}{(1/5)}\frac{h}{km} \\ \\x=\frac{(1/5)}{(1/12)} \\ \\x=\frac{12}{5}\ h$

Convert to mixed number

$\frac{12}{5}\ h=\frac{10}{5}+\frac{2}{5}=2\frac{2}{5}\ h$
