Final answer:
To find how far Eric rode his bike, you need to multiply the distance he traveled by the fraction representing the fraction of the distance he rode his bike, which is 7/8 x 4/5. The result is 7/10.
Step-by-step explanation:
To find how far Eric rode his bike, you need to multiply the distance he traveled by the fraction representing the fraction of the distance he rode his bike. The expression is: 7/8 x 4/5.
To multiply fractions, multiply the numerators (top numbers) together and then multiply the denominators (bottom numbers) together. The result is the product of the two fractions. In this case, the calculation would be: (7/8) x (4/5) = (7 x 4) / (8 x 5) = 28 / 40.
To simplify the fraction, find the greatest common divisor (GCD) of the numerator and denominator and divide both by that number. In this case, the GCD of 28 and 40 is 4. Therefore, the simplified fraction is: 28 / 40 = 7/10.
