Answer:
a) To find out how many pounds a 137 ounce baby weighs, we divide the weight in ounces by the number of ounces per pound.
137 ounces / 16 ounces/pound = 8.5625 pounds
Therefore, a 137 ounce baby weighs 8.5625 pounds.
b) To find out how much heavier the second baby is, we first convert the weight of the second baby from pounds to ounces.
We know there are 16 ounces in one pound, so we can multiply 9.375 (9 3/8) by 16 to find out how many ounces the second baby weighs.
9.375 * 16 = 150.4 ounces
Now we can subtract the weight of the first baby from the weight of the second baby to find out the difference in weight.
150.4 - 137 = 13.4 ounces
Therefore, the second baby is 13.4 ounces heavier than the first baby.
