we can call guest x

1/3x+5/12x+69=total guests at the wedding

if we multiply 1/3 by 4 we get 4/12. we can add 4/12 to 5/12 to get 9/12 which can be reduces to 3/4. that means the vegetarian guests make up 1/4 of the wedding. if 69 is 1/4, then we have all the information we need to solve this


25%       69                                                                                                                   -----        ------                                                                                                                       100%        ?


we are solving for the question mark. this is just a diagram. we know 25% of the 100% of the guest and we know that we have 69 of the however many guest. multiply 100 by 69

100x69=6900

now divide 6900 by 25

6900/25=276 guests at the wedding

You need to first subtract everything on the numerator by changing the fractions in the numerator. Each fraction should have a similar denominator. You should end up getting 24/10, simplifying it down to 12/5. After that you multiply the fractions in the denominator part, due to the key word “of” indicating that you need to multiply. Once you do that you have your numerator and denominator simplified down from each equation, you then simplify down further.

Angelo chooses a number from 1 to 10. What is the probability that he chooses an odd number or a multiple of 5?
wel
Okay, so the possible numbers he can choose are :

1, 2, 3, 4, 5, 6, 7, 8, 9, 10

Pick out all the odd numbers and multiples of 5.

1, 3, 5, 7, 9, 10

Count how many numbers are odd and are a multiple of 5.

6 numbers are odd or are a multiple of 5.

So, out of 10 numbers, 6 are odd or are a multiple of 5,

Therefore, our answer is 6/10

If you would like it simplified, it would be 3/5

Or, as a decimal, it would be 60%
