Question

two lenght are in the ratio 7:8 If the first length is 278m what amount is the second length

Answer 1

Given,

The lengths are in the ratio $7:8$

The common product of the given ratio be $x$

The first length is $7x$

Given the value of first length is $278m$

$7x=278\\x=\frac{278}{7} \\x=39.7$

The second length is $8x$

Substitute the value of $x$ in $8x$

$=8(39.7)\\=317.7m$

Therefore the value of second length be $317.7m$.

Answer 2

Answer:

$317.7m$

Step-by-step explanation:

Given data,

Ratio of two lengths $=7:8$

The first length is $278m$

Let the first length be $7x$

$\Rightarrow 7x=278$

$\Rightarrow x=39.7m$

As per the given ratio, the second length is $8x$

$\Rightarrow 8x=8\times39.7=317.7m$

Hence, the second length is $317.7m$
