What's 7/8 + 7/12, no pictures

2 answers:

8 0

7/8+7/12 The denominators must be the same so we have to find the lcm of 8 and 12 which is 24. To get 24 you must multiply 8 by 3 and 12 by 2. Then u multiply the numerators by the same number you multiplied the denominators with. 8x3=24, 7x3=21 and 12x2=24, 7x2=14 = 21/24+ 14/24 Now we can add the numerators together and your denominators stay the same . 21+24=35 So now your answer is 35/24 Then you turn the improper fraction into a mixed number 24x1= 24 plus 11= 35 so your answer is 1 11/24

How many milliliters of 0.30%. sugar solution must you add to 75 mL of 4% sugar solution to get a 0.50% sugar solution? show you

LekaFEV [45]

We have 75 mL of 4% sugar solution.
We have to add a 30% sugar solution to make a 50% sugar solution.
75 * .04 + .30x = .50 * (75 +x)
3 + .30x = 37.5 +.50x
I can't get the equation to solve.
Did you type it correctly? For one thing, you have the percentages typed as .30 % and 4%. Are the decimal places in the correct positions?

Also, no matter how much 30% sugar solution you add, it will NEVER increase to 50%.
