Simple...

you have $\frac{3}{8}$ and $\frac{2}{5}$

Just subtract...but first find a common denominator...

Use 40 as the common denominator...

$\frac{3}{8} * \frac{5}{5} = \frac{15}{40}$
and
$\frac{2}{5} * \frac{8}{8} = \frac{16}{40}$

So, subtract,

$\frac{15}{40}
-
 \frac{16}{40}$

= $- \frac{1}{40}$

Thus, your answer.

Tom, Mary and Bill are aged 10,12 and 15 years respectively. They share 259 euros in the same ratio as their ages. Find how much

tigry1 [53]

Answer:

70 , 84 , 105

Step-by-step explanation:

sum their ages , 10 + 12 + 15 = 37

divide the amount by this sum to find the value of one part of the ratio.

259 ÷ 37 = 7 ← value of 1 part of the ratio , then

10 parts = 10 × 7 = 70 euros ← Tom's share

12 parts = 12 × 7 = 84 euros ← Mary's share
