Answer:
a) The mass of a box of bolts is greater.
b) 3/20 kg
Step-by-step explanation:
a) Firstly, you have to make the denominators of the two fractions the same (by finding the LCM of the denominators).
The LCM of 4 and 5 is 20.
Converting 3/4 into denominator 20:
= 15/20
Converting 3/5 into denominator 20:
= 12/20
Now comparing the numerators:
15 > 12
Hence,
3/4 > 3/5
b) Difference of the boxes can be done by subtracting the numbers with the same denominator:
15/20 - 12/20
= 3/20 kg

Answer:
the best estimate of the sum of 4 2/5 and 7 3/4 is about 12
Answer:
P = 25/42
Step-by-step explanation:
We are asked to calculate the probability that if two items are selected from two different boxes, what is the probability that bought are non-defective.
In the first box A, the probability of selecting a non-defective item is 5/7
In the second box B, the probability of selecting a non-defective item is 5/6
Now the probability of selecting 2 items, one from each of the boxes and both are non-defective are as follows;
5/6 * 5/7 = 25/42
235.24 + 45.58 = 280.82
280.82/2 = 140.41
each check was for $140.41
