A baby otter was born 3/4 of a month early. At birth, its weight was 7/8 kilograms, which is 9/10 kilogram less than the average weight of newborn otter in the aquarium. What is the average weight of a newborn otter?
7/8+ 9/10 = 1 31/40
The average weight of newborn otter is 1 31/40 kilograms
hope this helps
dude stop making stuff complicated i already gave the answer and that is all she/he/they/them needs to know
To find the average weight of a newborn otter, we need to calculate the weight of the baby otter at birth and then determine the difference between its weight and the average weight.
Given:
- The baby otter was born 3/4 of a month early.
- At birth, its weight was 7/8 kilograms, which is 9/10 kilogram less than the average weight of a newborn otter.
Step 1: Find the weight of the baby otter if it were born full-term.
Since the baby otter was born 3/4 of a month early, we need to add this time back to find its full-term weight. We'll use the concept of unitary method to adjust the weight proportionally.
Let's assume the average weight of a newborn otter is W kilograms.
Weight of the baby otter when born at full term = (7/8) kilograms + (9/10) kilogram
To add the fractions, we need to find the least common denominator (LCD) of 8 and 10, which is 40.
Weight of the baby otter when born at full term = (7/8)*(40/40) kilograms + (9/10)*(40/40) kilograms
= (35/40) kilograms + (36/40) kilograms
= (71/40) kilograms
Step 2: Calculate the average weight of a newborn otter.
Now, let's set up a proportion to find the average weight (W).
(71/40) kilograms / W kilograms = 1 (since the baby otter's weight is equal to the average weight without the difference)
To find W, we can cross-multiply and solve for it:
71/40 = W/1
Cross-multiplying gives:
71 = 40W
Dividing both sides by 40:
W = 71/40
Therefore, the average weight of a newborn otter in the aquarium is 71/40 kilograms or 1.775 kilograms.
Idk
sorry for not putting my name i am juicy friut and i help you
let the avg weight of a newborn otter be x
our otter weighed 7/8 kg
x - 7/8 = 9/10
times 40, the LCD
40x - 35 = 36
40x = 71
x = 71/40 = 1.775
The average weight of a newborn otter is 1.775 kg or 1775 g
check:
avg = 1775 g.
ours was 7/8 (1000) g = 875
difference is 1775-875 = 900
and 900 g just happens to be 9/10 kg
