Step-by-step explanation:
47/2443/1222/3Ответ:
Hey there here are your answers:
(1) 1 23/2 (2) 3 7/12(3) 7 1/3Explanation 1:
With unlike denominators find the Least Common Denominator (LCD):
LCD = 24
Multiplying numerators and denominators to get the LCD in all fraction denominators:
9/8 x 3/3 and 5/6 x 4/4
Then rewrite the equation with the equivalent fractions:
27/24 and 20/24
With like denominators we can operate on just the numerators:
27/24 + 20/24 (Don't add the denominators, keep them as 24)
Now simplify the
47/24 = 1 23/24
Explanation 2:
With unlike denominators find the Least Common Denominator (LCD):
LCD = 12
Multiplying numerators and denominators to get the LCD in all fraction denominators:
5/2 x 6/6 and 13/12
With like denominators we can operate on just the numerators:
30/12 + 13/12 (Don't add the denominators, keep them as 12)
Simplifying the
43/12 = 3 7/12
Explanation 3:
The two fractions have like denominators so you can add the numerators:
17/3 + 5/3 = 22/3 (Don't add the denominators, keep them as 3)
Now convert to mixed number:
7 1/3 is the final answer!
I hope this helps and have an amazing day!Ответ:
(-9/8)x - 7 + 7 = -25 + 7
(-9/8)x = -18
((-9/8)x)/(-9/8) = -18/(-9/8)
x = 18 × (8/9)
x = 16
