Answer 2

Answer:

Given:-

Find the value of x in $x : 5 = 28 : 35$

To Find:-

The value of "x"

Note:-

●》 Ratio is also as fraction

●》The 1st and 4th term in Ratio is extremes and 2nd and 3rd term in Ratio is mean.

●》The product of extremes is always = product of mean.

●》For finding x, here we needs to rearrange the term from its side to another as-

+ becomes -

- becomes +

× becomes ÷

÷ becomes ×

Solution:-

x : 5 = 28 : 35

☆ According to note first~

▪︎$x : 5 = 28 : 35$

▪︎$\frac{x}{5} = \frac{28}{35}$

☆ So according to note fourth point ( rearrangement )~

▪︎$x = \frac{28}{35} × 5$

☆ After doing multiplication~

▪︎$x = \frac{140}{35}$

After reducing in its lowest term~

▪︎$x = 4$

x = 4

Checking:-

Extremes = x, 35 and mean = 5,25

♤ Now let's check by, product of extremes = product of means ?

• $x × 35 = 5 × 28 \ \ ?$

♤ Applying the value

• $4 × 35 = 5 × 28 \ \ ?$

• $140 = 140 \ \ ?$

Yes !

Hence, proved that x = 4

Answer:-

The value of x = 4
