Answer:
3 7/9
Step-by-step explanation:
we have
3.77777... -----> is a repeating decimal
Let
x=3.7...
so
10x=37.7...
10x-x=37.7...-3.7...
9x=34
x=34/9
Convert to mixed number
34/9=(27/9)+((7/9)=3+(7/9)=3 7/9
Calculate both of those per hour:
2/3 crate / hour
1.25 crates / 2 hours = 5/8 crates / hour
2/3 + 5/8 = 16/24 + 15/24 = 31/24 per hour =
124 / 24 crates in 4 hours = 5 (4/24) crates =
5 (1/6) crates per 4 hours
