You can multiply them both as fractions or turn the fraction into a decimal and multiply it like that.
5 1/4 will have to turn into an improper fraction which means you have to get rid of the whole number so. To do so you have to multiply the whole number by the denominator which would be 5x4 which is 20 then add it to the numerator so I’d be 21.
Next turn the 3 into a fraction since it’s a whole number it’d be 3/1
Finally multiply straight across 21/4 x 3/1 which is 63/4 and luckily it’s already In it’s simplified form
Ok lets say
popcorn = x and
drinks = y
Jacob: 2x + 3y = 18.25
Zachary: 4x + 2y = 27.50
ok now you have to use these 2 equations to get the answer
4x + 2y = 27.50 ---> 2y = 27.50 - 4x ---> y = 13.75 - 2x
2x + 3y = 18.25
2x + 3(13.75-2x) = 18.25
2x + 41.25 - 6x = 18.25
-4x + 41.25 = 18.25
-4x = -23
x = 5.75 <u><em>One bag of popcorn is $5.75</em></u><em />
4x + 2y = 27.50
4(5.75) + 2y = 27.50
23 + 2y = 27.50
2y = 4.50
y = 2.25 <u><em>One drink is $2.25</em></u><em />
We can solve this by looking at pairs that equal 60.
6 and 10 get to 60 when multiplied. Let's see if it fits in as a perimeter.
12+20=32
So the width and length of the room is 6 meters and 10 meters.
600,000 i believe . just do 6000x10= 60,000 then times that by 10
7.914 * 10^-6 is 0.000007914 in scientific notation
