We know form our problem that 800 dollars are 560 pounds. so:

$(560pounds)/(800dollars) =0.7$ pounds per dollar.

Next, we are going to multiply our exchange rate by the number of dollars we want to change, 300:

$300dollars*(0.7pounds)/(dollar) =210pounds$

We will get 210 pounds for 300 dollars

55.04=43% of x
percent meas parts out of 100
43%=43/100=0.43

'of' means multiply

55.04=0.43 times x
diide both sides by 0.43
128=x

12.48 milliliters of medicine were separated into doses of 4 mL each. how many doses were made?

Answers

The number of doses are $\boxed{\bf3}$ , if each dose quantity is 4 mL and total medicine is 12.48 mL.

Further explanation:

The total quantity of the medicine in millilitres is 12.48.

The quantity of one dose in millilitres is 4.

To find the number of doses possible from 12.48 millilitres quantity of medicine with each doses has 4 millilitres quantity is calculated by the use of division.

Here, dividend is the quantity of all medicine and divisor is the quantity of each doses.

Substitute, number 12.48 for dividend and number 4 for divisor then obtain the quotient by the use of division as shown below.

$\begin{aligned}4\mathop{\left){\vphantom{1{12.48}}}\right.\!\!\!\!\overline{\,\,\,\vphantom 1{{12.48}}}}\limits^{\displaystyle\hfill\,\,\, {3.12}} \hfill\n\,\,\,\,\,\,\underline{12 \downarrow }\hfill\n\,\,\,\,\,\,\,\,\,04\hfill\n\,\,\,\,\,\,\,\,\,\,\,\,\underline{4\downarrow } \hfill\n\,\,\,\,\,\,\,\,\,\,\,\,08\hfill\n\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\underline8\hfill\n\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,0\hfill\n\end{aligned}$

The quotient of the above division is 3.12.

The number of doses is always being in natural number.

It is observed that nearest natural number for 3.12 is 3.

Thus, the number of doses are $\boxed{\bf3}$ , if each dose quantity is 4 mL and total medicine is 12.48 ml.

What is, 7 3/10+6 1/3+2 7/10?

Answers

7 3/10 + 6 1/3 + 2 7/10

First change them to improper fractions

73/10 + 19/3 + 27/10

now find the common denominator which would be 30

73/10 = 219 /30

19/3 = 190/30

27/10 = 81 /30

now add (219 + 190 + 81) = 490/30

now divide 490 ÷ 30 = 16 1/3

Your answer is 16 1/3

Hope this helps. :)

We are going to add 7 3/10 and 2 7/10 first. $\boxed{\boxed{7 (3)/(10)}}+\boxed{\boxed{2 (7)/(10)}}}=\boxed{\boxed{9 (10)/(10)}}$ . Now we are going to add $\boxed{\boxed{9{ (10)/(10)}}}$ by $\boxed{\boxed{6{ (1)/(3)}}}$ . $\boxed{\boxed{9{ (10*3)/(10*3)}}}=\boxed{\boxed{9{ (30)/(30)}}} \ and \ \boxed{\boxed{6 (1*10)/(3*10)}}}=\boxed{\boxed{6{ (10)/(30)}}}$ . Finnally we add. $\boxed{\boxed{9{ (30)/(30)}}}+{\boxed{\boxed{6{ (10)/(30)}}}=\boxed{\boxed{15 (40)/(30)}}}.$ . Last, but not least we simplify, $\boxed{\boxed{15{ (30:10)/(40:10)}}}=\boxed{\boxed{15 (3)/(4)}}}$ . Therefore, your answer is $\boxed{\boxed{15 (3)/(4)}}}$ . Hoped I helped. :)
