Answer:
31 1/6 feet
Step-by-step explanation:
add 25 2/3 to 5 1/2 to see how far under the surface he is; use common denominator of 6
25 4/6 + 5 3/6 = 30 7/6
30 7/6 is the same as 30 + 1 1/6 so diver must ascend 31 1/6 feet
I would say that its pair 1 and 3
I think you do multiplying fractions. So 1 1/2 x 20
Factor ||5||−||−5||−(−5)|5|-|-5|-(-5) = 25 =5² ( 2 prime factors, 1 distinct)
Divisors = 1,3,25 (3 divesors)
