Question

Write down two equivalent ratios for each of the following:

Answer 1

$\\ \sf\longmapsto \dfrac{750}{30}=\dfrac{250}{1}=250:1$

#2

$\\ \sf\longmapsto \dfrac{540}{480}=\dfrac{9}{8}=9:8$

#3

$\\ \sf\longmapsto \dfrac{60}{40}=\dfrac{2}{3}\implies R1:R2::3:2$

Answer 2

Key points :-

ꕥ Equivalent ratios are referred to as the ratios which are same when compared.

ꕥ To find a equivalent ratio, simplify the given ratio.

ꕥ One ratio can have two or more equivalent ratios.

$\red{ \rule{300pt}{3pt}}$

#2.1

$\green \longmapsto \tt \red {750: 30}$

• Write the ratio as a fraction

$\green \longmapsto \tt \red { \frac{750}{30} }$

• Reduce the fraction with 25

$\green \longmapsto \tt \red { \frac{25}{1} }$

• Thus, The equivalent ratio is 25:1...~

#2.2

$\pink \longmapsto \tt \purple {540 :480 }$

• Write ratio as a fraction

$\pink \longmapsto \tt \purple { \frac{540}{480} }$

• Write an equivalent fraction using multiplication i.e. multiply the numerator and denominator by the same number. I am taking 2

$\pink \longmapsto \tt \purple { \frac{540}{480} \times \frac{2}{2} = \frac{1080}{960} }$

• Thus, The equivalent ratio is 1080:960...~

#2.3

$\blue \longmapsto \tt \orange {60 :40}$

$\blue \longmapsto \tt \orange { \frac{60}{40} }$

$\blue \longmapsto \tt \orange { \frac{3}{2} }$

Thus, The equivalent ratio is 3:2...~
