4/5 x 2 is 1 3/5 or 1.6
4 and 5 are both times by 2
if you times 2 by 4, you get 8. if you times 7 by 4, you get 28. Also, 28 times 2 is 56 and 7 times 5 is 56. by cross multiplying, if you get the same answer the fractions are equal.
To simplify the expression ((4^5 \times 4^{-3})^{-2}), first combine the exponents: (4^{5 - 3} = 4^2). Then, raising it to the power of (-2) gives (4^{2 \times -2} = 4^{-4}), which is equal to (\frac{1}{4^4} = \frac{1}{256}). Therefore, the expression is equal to (\frac{1}{256}), confirming that it is equal to 1 over 256.
9/8 ("9 over 8")
Well 4 times 2 should be fairly straight forward (4*2=8) 2 over 5 means that 5 should be multiplicated by it self 2 times (5*5=25)
8/12 = 4/6 = 2/3 = 0.6666666666
3/2 x 3/4 = 9/8 or 1 and 1/8.
They are: 1 times 4 = 4 or 2 times 2 = 4
4
-4
37! times 4 is equal to 5.5055012e+43.7776 divided by 2 times (37! times 4) is equal to 2.1405389e+47.
lets say you have 2 and 3 over 4 you would times the bottom which is 4 to the mixed number which is 2 and it would equal 8 and then u add 3 which would equal to 11 over 4
