An ant has a mass of approximately 4 times 10 the power of -3 grams and an elephant has a mass of approximately 8 metric tons.
how many ants does it take to have the same mass as an elephant?

2,000,000,000 ants

Step-by-step explanation:

Ant's mass is   grams

Putting that into decimal [or converting scientific notation to decimal]

We have:

0.004 grams

Note: to the power -3 means taking the decimal point 3 places left, so we have 0.004 grams

To compare, we have to take the elephant's weight to grams.

Firstly, 1 metric ton = 1000 kg

So 8 metric ton = 1000 * 8 = 8000 kg

Now, we know 1000 grams = 1 kg, so

8000 kg = 8000 * 1000 = 8,000,000 grams

The elephants weight (in grams) is 8,000,000 grams

How many ants are there in this?? We simply divide and find:

8,000,000/0.004 = 2,000,000,000 ants

It takes 2,000,000,000 ants to equate the mass of one elephant

ian gone lie this got me confused

step-by-step explanation:

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.
