2 4/5
Division of fractions is easy - just turn the second one upside down and multiply.So 2 / 5 divided by 4 / 7is equivalent to 2 / 5 times 7 / 4which is equivalent to (2 times 7) / (5 times 4)= 14 / 20 = 7 / 10
To express (2^{-5} \times 28) as an exponential expression, we can first rewrite 28 in terms of base 2. Since (28 = 4 \times 7 = 2^2 \times 7), we can substitute this into the expression: [ 2^{-5} \times 28 = 2^{-5} \times (2^2 \times 7) = 2^{-5 + 2} \times 7 = 2^{-3} \times 7. ] Thus, the exponential expression is (2^{-3} \times 7).
2/5 * 4/7 just multiply through = 8/35
No because 4 is not a prime number. You would need to find the factors of 4 (2x2). 5, 7, 2 and 2 are prime numbers.
2*2 = 4 * 3 = 12 * 5 = 60 * 5 = 300 * 7 = 2,100

7/1 multiplied by 2/5 is 2 4/5 or 2.8
(7+7-2*2)/2=5 The solution is positive 5.
2/7 times 4/5 = 8/35
No because 4 is not a prime number. You would need to find the factors of 4 (2x2). 5, 7, 2 and 2 are prime numbers.
(3/4)(16/21)(7/10)=(2/5) or 2 over 5, or 2 fifths.
500/5 = 100 + 2 - 7 = 95 x 4 = 380
The answer is 3 times 2 and 3/5 = 7 and 4/5
7 x 5 x 4 = 140
