94
(2 x 60) - (2 x 13) = 2 x 47 = 94
It is 2*(60-13).
Rewrite the factors and product. 2*3^2*5 = 3^2*2*5
(4 x 9) + (5 x 9) = (9 x 9)c= 81
No.
No, it is not.
A mixed fraction is a rational number because you can rewrite it as one integer over another.
Tasha is correct. The simple subtraction problem 120 - 36 can be rewritten as the pointlessly obtuse (3 x 40) - (3 x 12) = 3 x 28 = 84. Left unexplained is why on earth she would want to do that.
The GCF in this case is 3. 75 + 18 = 93 93/3 = 31 Rewriting 31 as another sum seems unnecessary, but sure. (30+1) * 3 = 93 = 75 + 18.
You need at least two numbers to find a GCF, so this probably isn't a GCF problem. To rewrite 10 as a product of its prime factors, use 2 x 5.
48 = 24 x 3
16-2
Perform long division of the ratio.
You don't. Mixed numbers and whole numbers are separate things.
