<u>Answer:</u>

The solution of −3/8÷−6/7 is \frac{7}{16}

<u>Solution:</u>

The given equation is -\frac{3}{8} \div-\frac{6}{7}

In the above equation we can see that more than one mathematical operator has been used.

To figure out which one to solve first we need to follow the BODMAS rule.

BODMAS mean brackets, of, division, multiplication, addition and subtraction.

To make the calculation simply we will invert one of the fractions. This will make the division operator into a multiplication one.

-\frac{3}{8} \times-\frac{7}{6}

This equation can be simplified as 6 is divisible by 3. Also the negative signs cancel out each other.

\frac{1}{8} \times \frac{7}{2}

On multiplying the remaining terms we get;

\frac{7}{16}

Hence the solution of −3/8÷−6/7 is \frac{7}{16}

Can u please help me with 27
Pachacha [2.7K]
The answer would be 237.375. To get this answer, you will first use the formula given for each unit. First, you will do the first unit by putting 8 to the third power, or basically 8x8x8. After you get the product 512, you will then do the next unit. Do that one by doing 6.5 to the third power, or as followed, 6.5x6.5x6.5. Once you get the product 274.625, you will then subtract that from 512. You will then receive the answer 237.375.

Mr lim had just enough money to buy 6 similar lamps. However, he bought 3 such lamps and had $950 left. How much money did mr li
Artyom0805 [142]

Let the cost of a lamp = x

6 lamps would cost 6x

He bought 3 lamps at 3x plus Thad 950 left.

3 lamps plus the 950

Would be the same amount as 6 lamps:

Set up an equation and solve for x:

3x + 950 = 6x

Subtract 3x from both sides:

950 = 3x

Divide both sides by 3:

X = 316.67

Each lamp was $316.67

Multiply the price of a lamp by 6:

316.67 x 6 = 1900

He had $1900
