Question

12 cm : 15 cm and 16 km : 20 km​

Answer 1

Answer:

It's quit easy

Answer is one whole

Step-by-step explanation:

12 cm : 15 cm and 16 km : 20 km

• we will first see the cm one ;

therefore , 12 : 15 = 12 ÷ 15

therefore , it will be 4 / 5

• let us see second one ;

16 km : 20 km

therefore , 16 ÷ 20 = 4 / 5

• now finally we got both numbers as 4 / 5 and 4 / 5

[word of tip free from Me :- ]

when we get the word { and } we need to multiple both .

• therefore , 4 / 5 × 4/ 5 = 1
