Answer:
[tex]4 \frac{1}{4} [/tex] hours
Step-by-step explanation:
Given,
Time spent in studies : [tex]1 \frac{3}{4} [/tex] hours
Time spent in playing cricket : [tex]2 \frac{1}{2} [/tex] hours
Now, let's find the time that he spent in all:
[tex]1 \frac{3}{4} + 2 \frac{1}{2} [/tex]
Add the whole number and fractional parts of the mixed numbers separately
[tex](1 + 2)( \frac{3}{4} + \frac{1}{2} )[/tex]
Add the numbers
[tex]3 +( \frac{3}{4} + \frac{1}{2} )[/tex]
Add the fractions
[tex]3 + ( \frac{3 + 1 \times 2}{4} )[/tex]
[tex]3 + ( \frac{3 + 2}{4} )[/tex]
[tex]3 + \frac{5}{4} [/tex]
Convert the improper fraction into mixed number
[tex] 3 + 1\frac{1}{4} [/tex]
Write the mixed number as a sum of the whole number and the fractional part
[tex]3 + 1 + \frac{1}{4} [/tex]
Add the numbers
[tex]4 + \frac{1}{4} [/tex]
Write the sum of whole number and the fraction as a mixed number
[tex]4 \frac{1}{4} [/tex] hours
Hope this helps..
Best regards!!
Answer:
4 1/4 hours.
Step-by-step 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.
