46 people are going to the beach. Nine people can ride in each van. How many vans are needed?

6

Step-by-step explanation:

No. of people going to beach = 46 .

Using Unitary Method ,

9 people can go in one van .

1 person can go in 1/9

46 people can go in 1/9 * 46 = 5.1

Since vans can't be in fraction , 1 extra van for 1 person is need that is for 46th person .

So total number of vans = 5 + 1 = 6

the least common denominatore of 7 and 2 is 9

step-by-step explanation:

7+2=9
