Answer 1

To find out how many hours Michael spent training, we need to multiply 35 1/2 hours by 1 1/2.

To multiply a whole number by a fraction, we multiply the whole number by the numerator and divide by the denominator:

35 1/2 * 1 1/2 = (35 * 2 + 1) / 2 * 3/2

= (70 + 1) / 2 * 3/2

= 71 / 2 * 3/2

= 71 * 3 / 2 * 2

= 213 / 4

Therefore, Michael spent 53 1/4 hours training for the race.
