Help please!?
1)5/8 divided by 5?
2)45 divided by 3 3/4
3) 3/4 + 5/8
------------=
3/4 - 1/2
(5/8) / 5 =
(5/8) * (1/5) = 5/40 = 1/8
I'll be glad to check your answers for the rest -- Tammy, Dotti, daphinie, or Cathy.
Thanx! What about #2 & #3?
Of course, I'd be happy to help you with your math questions!
1) To divide 5/8 by 5, we can follow these steps:
- First, we need to convert the whole number 5 into a fraction with a denominator of 8. Since 5 is equivalent to 5/1, we can rewrite it as 5/1 for consistency.
- Then, we multiply the numerators (5 and 1), and the denominators (8 and 5) separately. This gives us 5/1 ÷ 5/8.
- To divide fractions, we invert the divisor (the second fraction) and multiply it by the dividend (the first fraction). So, we have 5/1 ÷ 5/8 = 5/1 × 8/5.
- Finally, multiply the numerators (5 × 8) and the denominators (1 × 5) to get the result. Thus, 5/1 × 8/5 = 40/5.
- Simplifying the fraction gives us the final answer: 40/5 = 8.
Therefore, 5/8 divided by 5 is equal to 8.
2) To divide 45 by 3 3/4, we can use the following steps:
- Convert the mixed number 3 3/4 into an improper fraction. Multiply the whole number (3) by the denominator (4) and add the numerator (3). This gives us (3 × 4 + 3)/4 = 15/4.
- Now, we divide 45 by 15/4. To divide fractions, we invert the divisor (15/4) and multiply it by the dividend (45). So, 45 ÷ 15/4 = 45 × 4/15.
- Multiply the numerators (45 × 4) and the denominators (1 × 15) to get the result. That is, 45 × 4/15 = 180/15.
- Simplifying the fraction gives us the final answer: 180/15 = 12.
Therefore, 45 divided by 3 3/4 equals 12.
3) To solve the equation (3/4 + 5/8) ÷ (3/4 - 1/2), we can follow these steps:
- First, let's simplify the fractions inside the parentheses. The common denominator for 4 and 8 is 8. So, we have (6/8 + 5/8) ÷ (6/8 - 4/8).
- Adding the numerators (6 + 5) gives us 11. The denominator remains the same, 8. Therefore, the equation becomes 11/8 ÷ (6/8 - 4/8).
- Now, let's subtract the fractions inside the parentheses. 6/8 - 4/8 equals 2/8.
- Replacing 2/8 with its simplified form, we have 11/8 ÷ 1/4.
- To divide fractions, we invert the divisor (1/4) and multiply it by the dividend (11/8). Thus, 11/8 ÷ 1/4 = 11/8 × 4/1.
- Multiply the numerators (11 × 4) and the denominators (8 × 1) to get the result. That is, 11 × 4/8 × 1 = 44/8.
- Simplifying the fraction gives us the final answer: 44/8 = 11/2.
Therefore, (3/4 + 5/8) ÷ (3/4 - 1/2) equals 11/2.
