Help please!?
1)5/8 divided by 5?
2)45 divided by 3 3/4
3) 3/4 + 5/8
------------=
3/4 - 1/2
1... mmhh ?
5/8 ÷ 5 = 1/8
2. 45 ÷ 3 3/4
mixed fractions are useless in calculations.
= 45 ÷ (15/4)
= 45(4/15) = 12
3. 3/4 + 5/8
------------=
3/4 - 1/2
= (11/8) / (1/4)
= (11/8)(4) = 11/2
Thanks!
Of course! I'll be happy to help you with your math questions:
1) To solve 5/8 divided by 5, you need to divide the numerator (which is 5) by the denominator (which is 8) first. So, 5 divided by 8 equals 0.625. Then, divide 0.625 by 5. The answer is 0.125.
2) To solve 45 divided by 3 3/4, you can convert the mixed fraction to an improper fraction. Multiply the whole number (which is 3) by the denominator (which is 4) and add the numerator (which is 3). This gives you 15/4. Then, divide 45 by 15/4. To divide by a fraction, you multiply by its reciprocal. So, you multiply 45 by the reciprocal of 15/4, which is 4/15. The answer is 12.
3) To solve 3/4 + 5/8, you need to find a common denominator for both fractions. The smallest number that both 4 and 8 divide into evenly is 8. Multiply the numerator and denominator of 3/4 by 2 to get 6/8. The fraction 5/8 remains unchanged. Now that both fractions have the same denominator, you can add the numerators together: 6 + 5 = 11. The answer is 11/8.
To subtract 3/4 - 1/2, you again need a common denominator. The smallest number that both 4 and 2 divide into evenly is 4. Multiply the numerator and denominator of 3/4 by 1 to get 3/4. Multiply the numerator and denominator of 1/2 by 2 to get 2/4. Now that both fractions have the same denominator, you can subtract the numerators: 3 - 2 = 1. The answer is 1/4.
I hope this helps! Let me know if you have any more questions.
