✈️Question✈️

• Find the unknown terms of each proportion 1.x:4=5:10.

✈️Solution✈️

1.x:4=5:10

$\frac{1.x}{4}=\frac{5}{10}$(by cross multiplying)

=>(1.x)×10=4×5

=>10x=20

=>x=$\frac{\cancel{10}}{\cancel{20}}$

=>x=$\frac{1}{2}$

Hence,x=0.5

So, the unknown proportion =1.5

Answer 2

Answer:

Question

Find the unknown terms of each proportion1x:4=5:10

Solution

$\bold{ \frac{1x}{4} = \frac{5}{10} }$

$\bold{ \to \: cross \: multiply}$

$\bold{\to1x \times 10 = 5 \times 4}$

$\bold{ \to{10x = 20}}$

$\bold {\to \: x = \frac{20}{10} } \\ \bold \green {\to \: x = 2}$

Therefore the value of x = 2
