Answer:
1.) The two pupils jogged in 5 5 /6 miles.
Solution:
2 1 /3 + 3 2 /4
= (2 + 3) + (1 /3 + 2 /4 )
= 5 + 1 × 4 /3 × 4 +2 × 3 /4 × 3
= 5 + 4 /12 + 6 /12
= 5 + 4 + 6 /12
= 5 + 10 /12
= 5 + 10 ÷ 2 /12 ÷ 2
= 5 + 5 /6
= 5 5 /6
2.) Only 4 1 /4 kg of chicken were left in the refrigerator.
Solution:
6 1 /2 – 2 1 /4
= (6 – 2) + (1 /2 – 1 /4 )
= 4 + 1 × 2 /2 × 2 – 1 /4
= 4 + 2 /4 – 1 /4
= 4 + 2 – 1 /4
= 4 + 1 /4
= 4 1 /4
3.) The two sisters make 13 1 /4 cups of tea for their visitors.
Solution:
7 3 /4 + 5 1 /2
= (7 + 5) + (3 /4 + 1 /2 )
= 12 + 3 /4 + 1 × 2 /2 × 2
= 12 + 3 /4 + 2 /4
= 12 + 3 + 2 /4
= 12 + 5 /4
= 12 +1 1 /4
= 13 1 /4
4.) She used 15 (?) meters of it.
