Turn it into a improper fraction and then multiply both the numerator and denominator together!
So like 1 1/2 x 2 1/2
Turn that into improper fractions and get 3/2x5/2
then you get 15/2 which is 7 1/2
Twice. Dividing by ten will move the decimal point one place to the left. Rather than dividing by ten twice, you can divide by 100 once.
Answer:
4th is correct answer. 1, 2, 3 not correct you can check the exponents properties
Using proportions, considering the weight of each bar and the ratio, it is found that the ship is carrying 52 gold bars.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three.
Each bar weighs 5 kg, and the total weight is of 600 kg, hence the number of bars is given by:
n = 600/5 = 120.
The proportion of gold bars is given by:
p = 13/(13 + 17) = 13/30
Hence, out of 120 bars, the number of gold bars is given by:
nG = 120 x 13/30 = 4 x 13 = 52.
