Marika multiplied 3/7 times 5/7 and got 15/7. Was her answer correct?
No, Marika's answer is not correct. The product of 3/7 times 5/7 is actually 15/49.
To determine if Marika's answer is correct, we need to multiply 3/7 by 5/7 and simplify the result.
To multiply fractions, we multiply the numerators together (3 * 5 = 15) and then multiply the denominators together (7 * 7 = 49).
So, 3/7 × 5/7 = 15/49.
Therefore, Marika's answer is incorrect. The correct answer is 15/49, not 15/7.
To verify if Marika's answer is correct, we need to multiply the fractions 3/7 and 5/7.
To multiply fractions, multiply the numerators together and multiply the denominators together. So, let's multiply:
3/7 * 5/7
The numerator is 3 * 5 = 15
The denominator is 7 * 7 = 49
Therefore, the multiplication of 3/7 and 5/7 is 15/49.
Since Marika's answer was 15/7 and the correct answer is 15/49, her answer is incorrect.
