1. Calculate: 3 4− 1 5. Type your fractional answer in the table below and press the button to check your work. Make sure the fraction is reduced.
To subtract fractions, we need to find a common denominator. In this case, the common denominator is 20.
The first fraction, 3/4, can be written as 15/20 (by multiplying the numerator and denominator by 5).
The second fraction, 1/5, can be written as 4/20 (by multiplying the numerator and denominator by 4).
Now, we can subtract the fractions: 15/20 - 4/20 = 11/20.
So, the answer is 11/20.
2. Simplify: 25 64. Type your fractional answer in the table below and press the button to check your work. Make sure the fraction is in simplest form (reduced).
To simplify the fraction 25/64, we need to find the greatest common divisor (GCD) of both the numerator and denominator, and then divide them by the GCD.
The GCD of 25 and 64 is 1 (since there are no common factors other than 1).
Dividing both the numerator and denominator by the GCD, we get:
25/1 ÷ 64/1 = 25/64.
Since the GCD is 1, we cannot reduce the fraction any further.
So, the simplest form of 25/64 is 25/64.
