1. Calculate the H.C.F of a 2 b 5 and a 3 b 3 .
harkovskaia [24]

Answer:

Step-by-step explanation:

Problem is HCF:

        Of;

                               a²b⁵      and     a³b³

The highest common factor, HCF is used to factor expressions in order to simplify them.

H.C.F is a factor that is common to both expressions.

       here we have

           a²b⁵    and      a³b³

     a²b⁵   = a x a x b x b x b x b x b

     a³b³  =  a x a x a x b x b x b

In both expressions, for a:

                        a x a            and   b x b x b x b x b

                        a x a x a      and    b x b x b

                    common factors are a and b

both entities contains a and b

  Highest common factor H.CF;

                          a²                and b³

               this makes   <em><u>a²b³     </u></em>      

<em><u>a²b³  </u></em> is common to both of them and it is the highest term that can be factored from the the two.

I NEED HILP PLS HOW IS THIS THE ANSWER....
Citrus2011 [14]

Answer:

The answer is correct, here's why:

Step-by-step explanation:

Dr. Silva's tank holds 15\frac{7}{8} gallons of gas.

She added 11.55 gallons to her tank to fill it up.

This means she must have had 5\frac{13}{40} gallons to start with because 5\frac{7}{8} - 11.55 = 5\frac{13}{40}
