Answer:
Fully grown kangaroo is 96000 times heavy than a newly born kangaroo.
Step-by-step explanation:
Given : A kangaroo weighs about 0.03 ounces at birth. Fully grown, it can weigh 180 pounds.
To find : How many times as heavy as a newborn kangaroo is a fully grown adult?
Solution :
Let the number of times the weight increases is 'x'.
New born weight of a kangaroo w= 0.03 ounce
Weight after fully grown = 180 pounds
Converting pounds into ounce,
1 pound = 16 ounce
180 pound = 180 × 16 = 2880 ounce
Full weight W=2880 ounce
According to question,
\(x\times w=W\)
Substitute the values,
\(x\times 0.03=2880\)
\(x=\frac{2880}{0.03}\)
\(x=\frac{2880\times 100}{3}\)
\(x=96000\)
Therefore, fully grown kangaroo is 96000 times heavy than a newly born kangaroo.
