PLZ help!!

Answer 1

Answer: OK. let's say you have 4 2/5+ 3 4/7. I am going to teach you how to add fractions with whole numbers.

step 1: take the whole numbers, and multiply them by the denominators, the numbers on the bottom of fractions. like this: on 4 2/5. multiply 4, (the whole number), by the denominator. 5 would be on the bottom. 4x5=20. then add the numerator to it. Now we have 22. take 22 as the numerator. put it over your original denominator, which was 5. you have 22/5. Do the same thing to 3 4/7.

step 2: Now you have 22/5 + 25/7. Find a number both of the denominators both multiply into. 5 and seven both go into 35. change 35 to both of the fraction's denominators.

step 3: Now you have 22/35 and 25/35. We know that to make 5 turn into 35, you multiplied it by seven. you also multiplied 7 by 5 to get 35. Now do the same thing to their numerators, the numbers on the top of the fractions. you changed 22/5 to 22/35. 5 times 7 equals 35. Now whatever you do to the denominator, you have to do to the numerator. so, you need to multiply 22 by 7 as well. Now you have 154/35. Do the same thing to 25/35 except multiply 25 by 5.

step 4: Now you have 154/35 + 125/35. If the denominators are the same, keep them the same on your final answer. Just add the numerators at this point. It would be 279/35.

step 5: Now to simplify! All you have to do is divide 279 by 35. 35 goes into 279 seven times with 34 left over. 7 will be the whole number. 34 will be part of the final fraction.
Take 35, our denominator from just a little while ago, keep it their, as the denominator. Since their is 34 left over, that is the numerator. The final answer is 7 34/35.

Answer 2

Answer: To Add fractions with whole numbers You have to
1. separate the whole number from the fraction part of each number
2.Add the whole numbers and then add the fractions again ,We will need to get common denominators so that we can add the fractions .The second fraction already has 10 as the denominator ,so we are ready to add .

Patricia scored 80% on a math test. She missed 4 problems. How many problems were on the test?

Answers

Answer: There are 20 problems on the test.

Step-by-step explanation:

Since we have given that

Patricia scored 80% on a math test.

She missed 4 problems.

So, 20% of the math test is equal to 4 problems.

Let the total number of problems on the test be x

According to question,

$(20)/(100)* x=4\n\nx=(100)/(20)* 4\n\nx=20$

Hence, there are 20 problems on the test.

There would be exactly twenty problems on the test for her to be able to get 80%.
You know it can't be ten because then that would make it 60% not 80% but if you add the first number of the percentage (8) and multiply it by two it will get you 16 then if you add 4 to that that would make it 20 and 16/20 equals 80%

Sarah gave the same answer when asked to round 4 7/8 to the nearest inch and half a inch. Explain why Sarah is correct.

Answers

when you take 4 7/8 and round it up to the next inch u round up because 7/8 is bigger than 1/2 so thats 5
u would round it up to 5 again for the nearest half inch because 7/8 is closer to 1 than 1/2 which brings it to 5
