To find out how many pieces of string that are 1/20 meter long Wyatt can cut, we need to divide the length of the whole string by the length of each individual piece.
Given that the whole string is 3/4 meter long and each piece is 1/20 meter long, we can set up the division like this:
(3/4) ÷ (1/20)
To divide fractions, we take the reciprocal of the divisor and multiply it by the numerator. Therefore, we can rewrite the division as:
(3/4) × (20/1)
Now, we can multiply the numerators and the denominators:
(3 × 20) / (4 × 1)
The numerator becomes 60 and the denominator becomes 4:
60/4
Finally, we simplify the fraction by dividing both the numerator and the denominator by their greatest common divisor, which is 4 in this case:
60 ÷ 4 / 4 ÷ 4
The final answer is:
15 pieces of string
(1/20) n = 3/4 = 15/20
n = 15
check:
15 pieces * 1/20 long = 15/20 = 3/4 sure enough
