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.
They are: 2^4 times 3 times 5^2 times 7 = 8400
2√20 - 3√7 - 2√5 + 4√63 = 2√(4 x 5) - 3√7 - 2√5 + 4√(9 x 7) = 4√5 - 2√5 - 3√7 + 12√7 = 2√5 + 9√7
3 and 2/7 + 4 and 5/73 + 4 = 7------------2/7 + 5/7 = 7/7, or 1--------------------------so,= 8====
2 * 3 * 5 * 7 = 210
2*2 = 4 * 3 = 12 * 5 = 60 * 5 = 300 * 7 = 2,100
1.4 times
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
2/5 * 4/7 just multiply through = 8/35
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.
500/5 = 100 + 2 - 7 = 95 x 4 = 380
(3/4)(16/21)(7/10)=(2/5) or 2 over 5, or 2 fifths.
7 x 5 x 4 = 140
