The correct equation of 146 ÷ 7 = 20857 is 146.0 ÷ 7.0 = 20.857

<h3>How to divide the decimals?</h3>

The equation is given as:

146 ÷ 7 = 20857

The above equation is wrong.

The equation can be rewritten as:

146.0 ÷ 7.0 = 20857

The significant digits in 146.0 and 7.0 are 3 and 1, respectively.

3 - 1 = 2

This means that

So, the decimal place in the result must be after the second digit.

So, we have:

146.0 ÷ 7.0 = 20.857

Using the above highlights, we have:

146 ÷ 0.7 = 208.57

1.46 ÷ 7 = 0.20857

14.6 ÷ 0.7 = 20.857

1460 ÷ 70 = 20.857

The reasoning behind the above equations is that the decimal position in the results is dependent on the decimal positions in the dividend and divisor

How many times do you subtract 7 from 1999 and 5 from 1701 to get an equal number?
blsea [12.9K]

Answer:

<h2>149 times.</h2>

Step-by-step explanation:

Let n be the number we are looking for.

The we have to solve this equation:

1999 - 7n = 1701 - 5n

⇔ 1999 - 1701 = 7n - 5n

⇔ 298 = 2 n

⇔ n = 298/2

⇔ n = 149

<u><em>Verification</em></u> :

1 999 - 7×149 = 956

1 701 - 5×149 = 956

Marina CMI [18]
30 inches of ribbon because in one foot there are 12 inches so in 2 feet there are 24 inches. And 30 is greater than 24 so therefore 30 inches of ribbon is longer than 2 feet of ribbon
