60 is what percent of 48?

Yakvenalex [24]

Answer:

80%

Inverted = 125%

Step-by-step explanation:

Simplify the fraction to the most simpliest number, which is 4/5. 4/5 = 80%.

If it’s inverted (as in 60/48), the most simpliest number is 5/4. 5/4 = 125%.

Write your answer in scientific notation (2.5•10^8)•(2•10^3)

ICE Princess25 [194]

Answer:

$5\times10^{11}$

Step-by-step explanation:

In order to get the answer to this question you will have to put the scientific notations into their number form then multiply, then change back into scientific notation form.

$(2.5\times10^8)\times(2\times10^3)$

Turn the notations into their number form:

$2.5\times10^8$

The exponent is positive so move the decimal point to the right:

$2.5\times10^8=250000000$

Do the same with the second notation:

$2\times10^3$

Since the exponent is positive move the decimal point to the right:

$2\times10^3=2000$

Now multiply:

$250000000 \times 2000 = 500000000000$

Now turn the number into scientific notation:

$500000000000 = 5.0\times10^{11}$

$=5\times10^{11}$

Hope this helps.
