Determine if the following ratios form a proportion. Also, write the middle terms and extreme terms where the ratios form a proportion.
200 mL : 2.5 litre and ₹ 4 : ₹ 50
उत्तर
200 mL : 2.5 litre and ₹ 4 : ₹ 50
1 litre = 1000 mL
2.5 litre = 2500 mL
`200/2500 = 2/25` and `4/50 = 2/25`
Yes. These are in proportion.
Middle terms are 2.5 litre, ₹ 4.
Extreme terms are 200 mL, ₹ 50.
