Answer:
Word problem based that can be solved using multiples to estimate the quotient:
Melissa made 326 cupcakes. She packed four cupcakes into each box. How many boxes of cupcakes did she pack? How many cupcakes were left unpacked?
Answer:
Let us consider,
The problem: 'Find two numbers between which the quotient of 50 ÷ 7 lies'.
Solution: We will solve this in two steps.
Step 1: Form a table of multiples of 7.
Counting number Multiple of 7
1 7
2 14
3 21
4 28
5 35
6 42
7 49
8 56
Step 2: Use the table to find the multiples closest to 50.
Since, 49 = 7 × 7 and 56 = 7 × 8
Thus, 50 lies between 49 and 56.
Then, the quotient is either 7 or 8.
As 50 is closest to 49.
Hence, the quotient of 50 ÷ 7 is 7.
By using mental math the value of 15/124·230/30÷230/124 is 1/2.
To get better at mental math or metal calculation we can start by practising doing arithmetic operations of two digit numbers.Then after we can go on increasing the digits when we're getting better at it.Thinking of the easiest way to chunks numbers also helps.
According to the given question
{(15/124)×(230/30)}/(230/124)
First the fraction (230/124) which is in the denominator we flip and multiply.
= (15/124)×(230/30)×(124/230)
Now 124 and 124 on numeration and denominator gets cancelled and same case is applicable for 230 then after we are left with 15/30 which is equal to 1/2.

Area of a rectangle= length*width
So:
Area of the playground= (6x)(4x+4)
Use distributive property.
Area of the playground= (6x*4x)+(6x*4)
=24x^2+24x
Answer: 24x^2+24x
