Question

Pls answer the image given

Answer 1

4 1/4 hours.

Explanation:

1 3/4 + 2 1/2

= 1 + 2 + 3/4 + 1/2

= 3 + 3/4 + 1/2 The LCM of 2 and 4 is 4 so 1/2 = 2/4. and so we have:

3 + 3/4 + 2/4

= 3 + 5/4

= 3 + 1 1/4

= 4 1/4 hours.

Answer 2

`4 (1)/(4)` hours

Explanation:

Given,

Time spent in studies :
`1 (3)/(4)` hours

Time spent in playing cricket :
`2 (1)/(2)` hours

Now, let's find the time that he spent in all:

`1 (3)/(4) + 2 (1)/(2)`

Add the whole number and fractional parts of the mixed numbers separately

`(1 + 2)( (3)/(4) + (1)/(2) )`

Add the numbers

`3 +( (3)/(4) + (1)/(2) )`

Add the fractions

`3 + ( (3 + 1 * 2)/(4) )`

`3 + ( (3 + 2)/(4) )`

`3 + (5)/(4)`

Convert the improper fraction into mixed number

`3 + 1(1)/(4)`

Write the mixed number as a sum of the whole number and the fractional part

`3 + 1 + (1)/(4)`

Add the numbers

`4 + (1)/(4)`

Write the sum of whole number and the fraction as a mixed number

`4 (1)/(4)` hours

Hope this helps..
