6 1/4 + 4 1/2 please help test

43/4 or 10 3/4

Step-by-step explanation:

6 1/4 + 4 1/2

6 1/4 can be converted into 25/4, and 4 1/2 can be converted into 9/2.

If you're confused on how to convert it, you can use the multiply denominator, add numerator method. For example, with 6 1/4, you multiply 6 by 4 and then add 1 to get 25. With that method, the value you get is your numerator, and the denominator stays the same.

25/4+9/2

In the expression, the LCD (least common denominator) is 4, so you can multiply the second fraction to get it to a denominator of 4.

25/4+18/4

43/4 or 10 3/4

answer is 67%

step-by-step explanation:

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.
