Answer:
[tex] 1\frac{1}{4} \: or \: 1.25[/tex]
Step-by-step explanation:
convert 1 3/4 into improper fraction: 7/4
we got this from 4 × 1 = 4, then 4 + 3 = 7
the denominator stays the same
we need to subtract the amount that he has left from
the total amount:
make the number 3 have the same denominator as 7/4
[tex]3 - \frac{7}{4} = \frac{3}{1} - \frac{7}{4} = \frac{4 \times 3}{1 \times 4} - \frac{7}{4} = \frac{12}{4} - \frac{7}{4} = \frac{5}{4} [/tex]
convert 5/4 into a mixed number:
the numerator has to be the same, so how many lots of 4 can go into 5 without a remainder? it is 1
4 × 1 = 4
1 is left over, so the numerator is 1
4 + 1 = 5
[tex]1 \frac{1}{4} [/tex]
