There are 9 numbers less than 10.  1,2,3,4,5,6,7,8,9
And there are 2 multiples of 15.  15,30
There are 11 of the 40 cards that are either less than 10 or multiples of 15,  so the answer is B

Six fifths of what number is 60?
Crazy boy [7]
<h3>Hey Buddy,</h3>

<h3>Answer :-</h3>

Answer is 72 .

<h3><u>Explanation :-</u></h3>

\frac{6}{5}  \: of \: what \: number \: is \: 60 \:

You probably , Know that the number above the fraction line is called the numerator and the number below it is called the denominator. To work out the fraction of any number, we first need to convert that whole number into a fraction as well .

• Any number can be converted to fraction if you use 1 as the denominator:

\frac{60}{1}

• So now that we've converted 60 into a fraction, to work out the answer, we put the fraction 6/5 side by side with our new fraction, 60/1 so that we can multiply those two fractions.

• convert the whole number to a fraction and then multiply the numerators and denominators.

\frac{6 \times 60}{5 \times 1}  =  \frac{360}{5}

• Our new fraction can actually be simplified down further. To do that, we need to find the greatest common factor of both numbers.

• You can use our handy GCF calculator to work this out yourself if you want to. We already did that , And the GCF of 360 and 5 is 5.

• We can now divide both the new numerator and the denominator by 5 to simplify this fraction down to its lowest terms.

\frac{360}{5}  = 72

\frac{5}{5}  = 1

• When we put that together, we can see that our complete answer is :-

\frac{72}{1}

<h3> Hence ,the complete and simplified answer to the question what is 6/5 of 60 is :- 72 .</h3>

<h3>Hope this helps you...!</h3>

<h3>#Carry on learning#</h3>

<h3>I hope you can understand !! </h3>
