adam, ming, and Clinton sold sandwiches in the ratio 4:7:3 to raise money fir their Scout troop. Ming sold 91 sandwiches. How many sandwiches did the three boys sell together

Answers

Answer 1

Answer:

Answer:

They sold 182 sandwiches all together.

Step-by-step explanation:

We now that the sell ratio is 4:7:3, where 4 represents Adam, 7 represents Ming, and 3 represents Clinton.

An important characteristic of ratios is that they have a constant of change, which we can calculate using Ming's sandwiches sold and his ratio. If we divided these facts, we have:

$(91)/(7)=13$

This means that the constant of change is 13, now, if Ada and Clinton are in the same ration, the must also have the same constant of change, this means that we can multiply 13 in each case to get the total amount of sandwiches sold:

$4(13)+91+3(13)=52+91+39=182$

Therefore, they sold 182 sandwiches all together.

Answer 2

Answer: 182 sandwiches in total, 91 sandwiches divided by 7 is 13. Multiply 13 by all the other numbers and add.

Answers

1) 1000 / 100 ⇒ 10 / 1 = 10
1000 ÷ 100 = 10
100 ÷ 100 =   1

2) 9/81 ⇒ 1/9
  9 ÷ 9 = 1
81 ÷ 9 = 9

3) 4/64 ⇒ 1/16
  4 ÷ 4 =   1
64 ÷ 4 = 16

The answer would be b because you first should look at all your choices for example b which is 6 so the fraction would be 6/8 then since 8divided by 4 the denominators is 2 you would also divide the numerator by 2 so 6 divided by 2 is three and that equals 3/4 hope you find this helpful do you can do the next problem
