Answer: 5/28 left over.

Step-by-step explanation:

Make both of the fractions have the same denominator:

4/7 x 4/4 = 16/28

1/4 x  7/7 = 7/28

Combine:

16/28 + 7/28 = 23/28

So on Friday you have 5/28 of the item left over.

Answer:

5/28

Step-by-step explanation:

So first find a common denominator

4/7 + 1/4 can be translated as 16/28+7/28

16/28+7/28=23/28

NOw we have to subtract 23/28 from1, or 28/28, and that is 5/28

Round 0.687 yo the nearest tenths place
Vaselesa [24]

Answer: 0.7

Locate the tenths place which is just to the right of the decimal point. We see a 6 in this spot. Just to the right of this 6 is the value 8. Since 8 is larger than 5, we bump the 6 up to 7 and erase everything else to the right. You can think of it like this

0.687 ---> 0.6 which bumps up to 0.7

This is like saying 687 is closer to 700 than it is to 600

Find the product of √3 and 5√3 in simplest form. Also, determine whether the
pshichka [43]

The product of √3 and 5√3  in its simplest form is 15.

<h3>What is a rational number?</h3>

A rational number is defined as a numerical representation of a part of a whole that represents a fraction number.

It can be a/b of two integers, a numerator a, and a non-zero denominator b.

To determine the product of √3 and 5√3

So, (√3 )(5√3)

⇒ 5 (√3 )(√3 )

⇒ 5(3)

⇒ 15

The result is rational because 15, can be expressed as a ratio of two integers can be 15/1 of two integers, a numerator 15, and denominator 1 ( which is a non-zero).

Thus, the result is rational.

ASAP PLEASE HELP An ostrich egg has a mass of 1.2 kg to the nearest tenth of a kilogram. Find the minimum and maximum possible m
katen-ka-za [31]

The maximum possible measurement is 1.25 Kg and the minimum possible measurement is 1.15 kg

<u>Solution:</u>

Given mass of an ostrich egg is 1.2 Kg

We have to find the minimum and maximum possible measurements to the nearest tenth of a kilogram

The greatest possible error in measurement nearest tenth of a kilogram, is a half a tenth of a kilogram which is:-

\frac{1}{2} \times \frac{1}{10}=\frac{1}{20}

Now, the maximum value will be equal to calculated amount plus the error in measurement of value .i.e.

\text { Maximum value }=1.2+\frac{1}{20}=1.2+0.05=1.25

Now, the minimum value will be equal to calculated amount minus  the error in measurement of value .i.e.

\text { Minimum value }=1.2-\frac{1}{20}=1.2-0.05=1.15

Hence, maximum possible measurement is 1.25 Kg

And the minimum possible measurement is 1.15 kg
