Subtract: 7 7/10-3 4/5 =
4 3/5
4 1/10
3 9/10
11 5/10
Correct Answer : C
Convert the mixed fractions into improper fractions as:
\(7 7/10=\frac{\left(10\ast7\right)+7}{10}=\frac{70+7}{10}=\frac{77}{10}\)
\(3 4/5=\frac{\left(5\ast3\right)+4}{5}=\frac{15+4}{5}=\frac{19}{5}\)
Now, subtract the improper fractions as:
\(77/10-19/5=(77-19(2))/10=(77-38)/10=39/10\)

Correct Answer is D
Explanation
\(\frac{x}{4}\ =\ \frac{9}{x}\)
Cross-multiply the above proportion equation
\(X^2=9\ast4\)
\(X^2=36\)
Take square root on both sides
\(\sqrt{X^2}=\sqrt{36}\)
\(X=+6\ or-6\)
Taking the positive square root, X=6
Correct Answer is ["11"]
Explanation
The number of boys in a class is 44% of 25 students
44%of25
Convert 44% to fraction and carry out the multiplication as follows
\(\frac{44}{100}\ast25=11\ boys\)
Thus, there are 11 boys in a class of 25 students.
Correct Answer is D
Explanation
The ratio 0.6:X=7:42 can be written in proportion as:
\(\frac{0.6}{X}=\frac{7}{42}\)
The value of X is determined by cross-products
\(0.6\ast42=7X \)
25.2=7X
Divide both sides by 7
\(\frac{25.2}{7}=\frac{7X}{7}\)
\(3.6=X\)
Thus, the value of X is 3.6
Correct Answer is D
Explanation
Use substitution method to determine the value of the given expression. Use 3 in place of X in the given expression.
\(3X^2-\frac{21}{3}X\)
In place of X insert 3
\(3\left(3\right)^2-\frac{21}{3}\left(3\right)=3\left(9\right)-21=27-21=6\)
When X=3, the equation reduces to 6.
