[priya.j26]

Hi there

I need someone's help in solving these questions...

1. 34 orange cream biscuits and 46 pineapple cream biscuits are packed into small packets in equal numbers. FInally 10 biscuits of each kind remain after packing . FInd the maximum number of biscuits packed in each packet?

2. Clock 1 chimes every 30 minutes and clock 2 chimes every 45 minutes. They have just chimed together. When will they chime together again?

Simplify

1. 3 2/5 * 1 1/10 * 1 2/17

2. 3 2/3+ 1 1/2-( 3/4 +6/7)

3. 1/4 divided by { 5/7 - 1/3-1/4}

4. 1 2/3+[ 3 1/2-{2 1/3(6 1/2 divided by25)}]

5. [2 1/4-{(1/4+1/5-1/6+1/10)}]

6. 3[12+{11+13(15-9)}]

please let me know the steps to solve the above questions.

Thanks in advance

Re: Fractions

On fractions:
do you understand that (a/b) / (c/d) = (a/b) * (d/c) ?
or that a/b + a/c = (ab + ac) / (bc) ?

If not, only your teacher can help you...

Hi priya.j26:

You made the following request.

... please let me know the steps to solve the above questions.

Here are the steps for the first problem #1.

1. Subtract the amount left over from the starting number of each type of biscuit to discover the total number of each type packaged[/*:m:33kjzutq]
2. Find the largest number that evenly divides both numbers discovered in step 1[/*:m:33kjzutq]
3. Divide both numbers from step 1 by the number you found in step 2; the results are the two answers[/*:m:33kjzutq]

Here are the steps for the first problem #2.

1. Both clocks chimed together right now; start an imaginary stop watch[/*:m:33kjzutq]
2. Write a list showing the number of elapsed minutes on the stop watch for each of the next four chimings of clock 1[/*:m:33kjzutq]
3. Write a list showing the number of elapsed minutes on the stop watch for each of the next four chimings of clock 2[/*:m:33kjzutq]
4. Compare the list from step 2 with the list from step 3 to find the lowest number that appears in both lists; this number is the answer[/*:m:33kjzutq]

Here are the steps for the second problem #1.

1. Convert each of the three mixed numbers into improper fractions[/*:m:33kjzutq]
2. Multiply the first two improper fractions from step 1 together[/*:m:33kjzutq]
3. Multiply the result from step 2 times the last improper fraction in step 1; the result is the answer[/*:m:33kjzutq]

Here are the steps for the second problem #2.

1. Convert each of the two mixed numbers into improper fractions[/*:m:33kjzutq]
2. Add the two fractions inside the curly braces[/*:m:33kjzutq]
3. Subtract the result from step 2 from the fraction that appears to the left of the minus sign[/*:m:33kjzutq]
4. Add the result from step 3 to the fraction that appears to the left of the first plus sign[/*:m:33kjzutq]

Oh, I'm out of time. Here is the step for problem #3 through problem #6.

1) Do the arithmetic by following the Order of Operations

If you would like us to check your answers, then please post your work. We'd be very happy to look it over. And if you have any specific questions about these types of problems, then please ask. We really like to see that, as well.
