And encourage them that they are smart and don’t need this website help them even not with smarts just with confidence I used this website then I got some encouragement and now I just try to stop people like you Mrs.Solland!
To subtract fractions and reduce them, you need to find a common denominator for the fractions involved. Here's how you can calculate the answers to these questions and check your answers:
1. For 5/7 - 3/10:
- The least common multiple (LCM) of 7 and 10 is 70. So, multiply the numerator and denominator of 5/7 by 10, and multiply the numerator and denominator of 3/10 by 7:
(5/7) * (10/10) - (3/10) * (7/7) = 50/70 - 21/70 = 29/70
Your answer of 29/70 is correct.
2. For 11/18 - 5/12:
- The LCM of 18 and 12 is 36. Multiply the numerators and denominators accordingly:
(11/18) * (2/2) - (5/12) * (3/3) = 22/36 - 15/36 = 7/36
Your answer of 7/36 is correct.
3. For 1/3 - 1/6:
- The LCM of 3 and 6 is 6. Multiply the numerators and denominators accordingly:
(1/3) * (2/2) - (1/6) * (1/1) = 2/6 - 1/6 = 1/6
Your answer of 1/6 is correct.
4. For 7/12 - 1/16:
- The LCM of 12 and 16 is 48. Multiply the numerators and denominators accordingly:
(7/12) * (4/4) - (1/16) * (3/3) = 28/48 - 3/48 = 25/48
Your answer should be 25/48 instead of leaving it as "?".
5. For 7/8 - 3/10:
- The LCM of 8 and 10 is 40. Multiply the numerators and denominators accordingly:
(7/8) * (5/5) - (3/10) * (4/4) = 35/40 - 12/40 = 23/40
Your answer of 23/40 is incorrect. The correct answer is 23/40.
6. For 7/8 - 1/12:
- The LCM of 8 and 12 is 24. Multiply the numerators and denominators accordingly:
(7/8) * (3/3) - (1/12) * (2/2) = 21/24 - 2/24 = 19/24
Your answer of 19/24 is correct.
7. For 7/10 - 2/5:
- The LCM of 10 and 5 is 10. Multiply the numerators and denominators accordingly:
(7/10) * (1/1) - (2/5) * (2/2) = 7/10 - 4/10 = 3/10
Your answer of 3/10 is correct.
8. For 3/4 - 1/2:
- The LCM of 4 and 2 is 4. Multiply the numerators and denominators accordingly:
(3/4) * (1/1) - (1/2) * (2/2) = 3/4 - 2/4 = 1/4
Your answer of 1/4 is correct.
So, out of your answers, 7 are correct, and 1 is incorrect. The correct answer for question 5 is 23/40, not 46/80.
