Answer 1

Answer:

$1\frac{1}{4} \: or \: 1.25$

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

$3 - \frac{7}{4} = \frac{3}{1} - \frac{7}{4} = \frac{4 \times 3}{1 \times 4} - \frac{7}{4} = \frac{12}{4} - \frac{7}{4} = \frac{5}{4}$

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

$1 \frac{1}{4}$
