**math 4th grade**

Do you know how to change a fraction into a decimal without using the calculator?

**math 4th grade**

you can change all the fractions so that they have common denominators (bottom numbers)then compare the numerators (top numbers). Considering you are in 4th grade, I am wondering if the 2nd fraction (3/50) is supposed to be 3/5?

**algebra**

if you distribute the 6 it would look like this: (6 x 30) + (6 x 7) 6 x 30 = 180 6 x 7 = 42 When you add 180 & 42, you get 222

**Algebra - 9th grade**

please solve for either x or y: x/2 + y/4 = 7

**Math**

If you look at these decimals as money (coins) it will probably be easier - you will have to change the 8/10 into 0.80 first I would put that first & the 0.888 last also, you have 0.81 2x in your answer 8/10, 0.81, 0.8181, 0.888

**Math**

just in case you're still stuck on the 2nd & 3rd ones - one more thing to remember: when you add/subtract fractions, they need common denominators #2) (-3)-2.2-9-(-12)= (-3) - 2.2 = -5.2 - 9 - (-12) -5.2 -9 = -14.2 -(-12) *remember the -(-12) is really adding -14.2 + 12 = ...

**Math**

you have to remember that when you subtract a negative, you really add it - the () were used in your problems to section off numbers 8-(-2/3) would be the same as 8 + 2/3
