Work out: \(\frac{3}{5}\) of 7 kg.
Answer (3)
Well OF means to MULTIPLY So Ur pretty much looking at it like this: 3/5 x 7 You have to do 7 times the numerator, (which is 3) 7 times 3 is 21. Now we have 21/5 So 21/5 is the answer
5 3 ∗ 7 k g = 5 3 ∗ 7 k g = 5 21 k g = 4 5 1 k g = 4.2 k g
The calculation of 5 3 of 7 kg results in 5 21 kg, which is equivalent to 4.2 kg. You achieve this by multiplying the fraction with the total mass. Thus, 5 3 of 7 kg is 4.2 kg.
