Fittoniya [83]

Answer:

Step-by-step explanation:

Comment

I would think Pakistan should be more than just 4 times as large as Kenya. However if you are given that Kenya is 50 000 000 then Pakistan will be 4 times the size of Kenya.

Pakistan = 4 * Kenya

Pakistan = 4 * 50 000 000

Pakistan = 200 000 000

Answer: Pakistan = 200 000 000

Answer:

0.67

Step-by-step explanation:

To solve this we are going to use this lovely equation

P%•X=Y

Y is our end product

X in this case is 45

and P% is our percent

Now let's multiply 4% which becomes .004 by 45 and we get 1.8 which since there isn't 1.8 in American currency that becomes $1.80

We do the same process with the 2.5

0.025•45=1.125

Again not in the American currency so we will round 5 up and now we have $1.13

Now we subtract 1.80-1.13 which gets us 0.67 cents.

Hope I was helpful,
