Question

An alloy consists of 3 1/2 gm of copper and 2 3/4 gm of tin.find the ratio of copper to that of tin in the alloy in the simplest form

Answer 1

Answer:

Ratio of the copper to that of tin in the alloy is 14 : 11 .

Step-by-step explanation:

As given

An alloy consists of $3 \frac{1}{2}$ gm of copper and $2 \frac{3}{4}$ gm of tin.

It is also written as

An alloy consists of $\frac{7}{2}$ gm of copper and $\frac{11}{4}$ gm of tin.

$\frac{Weight\ of\ copper}{Weight\ of\ tin}= \frac{\frac{7}{2}}{\frac{11}{4}}$

Simplify the above

$\frac{Weight\ of\ copper}{Weight\ of\ tin}= \frac{7\times 4}{2\times 11}$

$\frac{Weight\ of\ copper}{Weight\ of\ tin}= \frac{7\times 2}{1\times 11}$

$\frac{Weight\ of\ copper}{Weight\ of\ tin}= \frac{14}{11}$

Therefore the ratio of the copper to that of tin in the alloy is 14 : 11 .

Answer 2

Answer:

14:11 ratio these is right
