Answer: 4 9/10
Step-by-step explanation: You need to subtract 12 2/5 and 7 1/2.
The two fractions have different denominators. Multiply to find a common denominator
2/5 x 2/2 = 4/10
1/2 x 5/5 = 5/10
Now you have 12 4/10 minus 7 5/10. But you cannot subtract 4/10 and 5/10 equally.
Subtract 12 - 1 and add 1 to 4/10.
12 - 1 = 11
10/10 (10/10 is 1) + 4/10 = 14/10
Now you have 11 14/10 minus 7 5/10. Subtract.
11 - 7 = 4
14/10 - 5/10 = 9/10
That makes 4 9/10.
Hope this is helpful :)
The answer is 18. You add 5 to both sides of the equation. the 5 cancels out. You are left with 2/3x=12. Then you divide 12 by 2/3 to get x. 12 divided by 2/3 is 18
It's the mean of (2.57 x 10) minus 4
The mean is the average.

The quotient of 2.28 × 5.59 using compatible numbers is approximately 12.75
<h3>What are products?</h3>
Quotients are result derived from the multiplication of two rational or integers. Given the expression
2.28 × 5.59
Convert to fraction
2.28 × 5.59 = 228/100 ÷ 559/100
2.28 × 5.59= 127452/10000
2.28 × 5.59= 12.75
Hence the quotient of 2.28 × 5.59 using compatible numbers is approximately 12.75
