this is the correct answer
mark me as brilliant
Write in the standard form.
1. 25/50 = 1/2
Explanation:
- = 25/50
- = (25 ÷ 5)/(50 ÷ 5 )
- = 5/10
- = (5 ÷ 5)/(10 ÷ 5 )
- = 1/2
No more common factor and 1 and 2 are co-prime so this is the standard form of 25/50.
2. 40/- 45 = - 8/9
Explanation:
- = 40/ - 45
- = - (40 ÷ 5)/(45 ÷ 5 )
- = - 8/9
- 8 and 9 doesn't have any common factors further. So, this is the standard form of 40/ -45. Remember the minus ( - ) sign in the given standard form.
3. - 18/- 81 = 2/9
Explanation:
- = - 18/- 81
Minus and minus sign in both numerator and denominator gets cancel, we have:
- = 18/81
- = ( 18 ÷ 3)/(81 ÷ 3)
- = 6/27
- = ( 6 ÷ 3)/(27 ÷ 3)
- = 2/9
5. 16/20 = 4/5
Explanation:
- = 16/20
- = (16 ÷ 2)/(20 ÷ 2)
- = 8/10
- = (8 ÷ 2)/(10 ÷ 2)
- = 4/5
6. -48/84 = - 4/7
Explanation:
- = -48/84
- = - (48 ÷ 4)/(84 ÷ 4)
- = - 12/21
- = - ( 12 ÷ 3)/(21 ÷ 3)
- = -4/7
7. 77/-49 = - 11/7
Explanation:
- = 77/-49
- = - ( 77 ÷ 7)/(49 ÷ 7)
- = - 11/7
9. 9/-10 or - 9/10
This is the standard form because 9 and - 10 does not have any more common factors and hence they are co-prime.
10. -13/-52 = 1/4
Explanation:
- = -13/-52
Minus and minus sign in numerator and denominator cancels each other, we get:
- = 13/52
- = 1/4
11. -9/27 = - 1/3
Explanation:
- = - 9/27
- = - ( 9 ÷ 3)/(27 ÷ 3)
- = - 3/9
- = - ( 3 ÷ 3)/(9 ÷ 3)
- = - 1/3
