(3 times 2 +1 over 2, and 3 times 2 plus 1 over 3)
7/2 * 7/3 Do this by multiplying the front numbers by the bottom numbers, and adding the top number. then place the final number on top, and keep the bottom number the same.

then multiply the fractions by multiplying the two tops, and the two bottoms.

49/6 Then reduce the fraction.

Work out (5.32 x 10^-7): (2.5 x 10^-5)<br>Give your answer in standard form

Mrrafil [7]

Answer:

1.33×10^-6

Step-by-step explanation:

5.32 x 10^-7= 5.32×10^(-5-2)= 5.32×10^-2×10^(-5)

=0.0532×10^-5

(0.0532×10^-5) (2.5 x 10^-5)

0.0532×2.5 × 10^-5

0.133×10^-5= 1.33×10^-1 ×10^-5

1.33×10^-6

The population of turtles is doubling every 3 months. If there are 400 turtles now, how many will there

QveST [7]

First we need to know how many months is 2 years. To answer that we multiply the number of months in a year by 2 and get 48 months.

Every 3 months the population of turtles doubles, but to get how many times the population doubles, you need to divide 48 months by 3 to get 16.

So population of 400 will get <u>doubled</u> 16 times in the following <u>two</u> years.

We construct the following equation where $p$ is the final population,

$p=400\cdot2\cdot16=\boxed{12800}$

Hope this helps. :)

1/7 x X =1 <br> X x 1/11=1<br> 1 divided by 1/5=

guajiro [1.7K]

Answer:

x = 7
x = 11
5

Step-by-step explanation:

$\frac{1}{7} \times x = 1$

$7 \times \frac{1}{7} x = 7 \times 1$

$7 \times \frac{1}{7} x = 7$

$\boxed{\green{x = 7}}$

◇◇•◇◇

$x \times \frac{1}{11} = 1$

$\frac{1}{11} x = 1$

$11 \times \frac{1}{11} x = 11 \times 1$

$11 \times \frac{1}{11} x = 11$

$\boxed{\green{x = 11}}$

♤♤•♤♤

$1 \div \frac{1}{5} = 1 \times \frac{5}{1}$

$1 \times 5$

$\boxed{\green{= 5}}$
