​

Answer 1

Answer:

See, 1/3:1/4 means 1/3÷1/4

Step-by-step explanation:

So, 1/3÷1/4

1/3×4=4/3

Answer 2

Step-by-step explanation:

1/3 : 1/4

= 1/3/1/4

= (1×4)/(3×1)

= 4/3

if you want to add 1/3 and 1/4, then

1/3 + 1/4

(the denominators(3, 4) are not same so we take here LCM of 3 and 4, which is 12, now make the denominators = 12

If we multiply 3 by 4 we get 12 , we will have to multiply by 4 to the numerator also,)

(1×4)/(3×4) + (1×3)/(4×3)

= 4/12 + 3/12

( now the denominators are the same, now add up the numerators, but not the denominators)

4/12 + 3/12 = 7/12
