Tristan rode his bike 3 2/3 miles on saturday he rode 1 4/5 mi on sunday how many more miles did he ride on saturday then on sunday a.1 3/15 miles b.1 3/5 c.1 13/15 d.2 13/15

c. 1 13/15

Step-by-step explanation:

The best way to find out how much more Tristan rode his bike would be to subtract both of his distances together.

Saturday =

Sunday =

Now we actually have two different fractions with different denominators.

We can solve this first by converting the mixed numbers into improper fractions.

Now how did I do that?

First we take the denominator and multiply it to our whole number, then add the product to the numerator.

Let's proceed to the next mixed fraction.

We are then left with:

Since we cannot subtract them directly because they have different denominators, we need to find the LCD of both denominators.

Now that they have similar denominators, we can then proceed to subtract them to each other.

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!

i would be happy to . most people on would also love to i'm sure. if you just want someone who has done algebra before and want a little more personal relationship than just begging strangers for , i can certainly be of service. i do have college myself so i might not be 24/7.
