Explain how you might use the properties of multiplication to solve 5 × 120 × 6.232 mentally. Then solve.
zysi [14]

Answer:

Follows are the solution to this question:

Step-by-step explanation:

In this question, we apply the associative property that calculates the given  value, which can be defined as follows:  

Rule:

\bold{\to (A\times B)\times C=  A \times (B\times C)}

Let,

A= 5\\B=120\\C=6.232

put the value in the above rule:

Solve L.H.S part:

\to (5\times 120)\times 6.232\\\\\to (600)\times 6.232\\\\\to 3,739.2

Solve R.H.S part:

\to 5 \times (120 \times 6.232)\\\\\to 5 \times 747.84\\\\\to 3,739.2

So, L.H.S=R.H.S

Roman55 [17]

Answer:

number of yellow marbles=62.

Step-by-step explanation:

It is given that in a bag there are yellow marbles and blue marbles and the total number of marbles=73.

Let the number of Blue marbles=x, then according to the question, number of yellow marbles will be =5x+7.

Now, Total number of marbles= number of yellow marbles+number of blue marbles.

⇒73=x+5x+7

⇒73-7=6x

⇒66=6x

⇒x=11

Therefore, numberof blue marbles=x=11 and

number of yellow marbles=5x+7=5(11)+7=55+7=62.
