Jack had moved to England from the United States. When he went to the physician's office, he was told that he weighed 11 1/2 stones. How much did he weigh in pounds? (One stone = 14 pounds.)
To find out how much Jack weighed in pounds, we need to multiply 11 1/2 stones by 14 pounds/stones.
To multiply a mixed number like 11 1/2, we multiply the whole number part and the fractional part, separately.
11 * 14 = <<11*14=154>>154
1/2 * 14 = 7
Adding the two results together: 154 + 7 = <<154+7=161>>161
So, Jack weighed 161 pounds. Answer: \boxed{161}.
To convert Jack's weight from stones to pounds, we need to multiply the weight in stones by 14, as 1 stone is equal to 14 pounds.
Given that Jack's weight is 11 1/2 stones, we can represent this as 11 (whole number) + 1/2 (fraction) stones.
First, we convert the fraction to an improper fraction:
1/2 = (1 * 2 + 1) / 2 = 3/2
Now, we need to add the whole number and the fraction together:
11 + 3/2
To add the whole number and the fraction, we need to find a common denominator:
11 = 11/1 (by multiplying numerator and denominator by 1)
3/2 = (3 * 2) / (2 * 2) = 6/4 (by multiplying numerator and denominator by 2)
Now, we can add the fractions:
11/1 + 6/4
To add the fractions, we need to find a common denominator. In this case, the lowest common multiple of 1 and 4 is 4:
11/1 = (11 * 4) / (1 * 4) = 44/4
6/4 = (6 * 1) / (4 * 1) = 6/4
Adding the fractions:
44/4 + 6/4 = (44 + 6) / 4 = 50/4
Now, we can simplify the fraction:
50/4 = (50 / 2) / (4 / 2) = 25/2
Finally, we multiply the resulting fraction by 14 (since 1 stone = 14 pounds):
25/2 * 14 = (25 * 14) / 2 = 350/2 = 175
Therefore, Jack weighs 175 pounds in the United States.
