nika is making cakes for a bake sale at school when she realizes she is running out of milk, each cake requires 1/4 cups of milk. nika has 3 3/4 cups of milk how many cups can she make

Nika can make 15 cups of milk.

Step-by-step explanation:

To find how many cups she can make, we divide 3 3/4 by 1/4. First, we convert 3 3/4 to an improper fraction.

3 ¾ / ¼           Equation

15/4 /  ¼         Convert to improper

15/4 * 4/1        Reverse sign & second fraction

= 60/4

= 15

Also, 15 * 1/4 = 3  ¾, so its correct!

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
