What is the product of 1 1/2 and -1 1/4?
Savatey [412]

positive number times negative number is negative number "(+)(-) = (-)".

1\dfrac{1}{2}\cdot\left(-1\dfrac{1}{4}\right)=-\left(1\dfrac{1}{2}\cdot1\dfrac{1}{4}\right)

we change the mixed numbers to the improper fractions

=-\left(\dfrac{1\cdot2+1}{2}\cdot\dfrac{1\cdot4+1}{4}\right)=-\left(\dfrac{3}{2}\cdot\dfrac{5}{4}\right)=-\dfrac{3\cdot5}{2\cdot4}=-\dfrac{15}{8}=-1\dfrac{7}{8}

 Jalen is painting her great room including the ceiling but not the floor. The room measures 20 ft long, 30 wide and 9 ft tall.
Luden [163]

4 cans of paint

\sf --->  \ \ {\boxed {\boxed {\frac{area  \ of \ room - area \ of \ floor}{area \ the \ paint \ covers} }}}

\hookrightarrow \sf {\dfrac{2(wl+hl+hw)- (lw)}{400}}

\hookrightarrow \sf {\dfrac{2((30)(20)+(9)(20)+(9)(30))-(20*30)}{400}

\hookrightarrow \sf {\dfrac{1500}{400}

\hookrightarrow \rm {\sf {3.75}}

→ She should buy max 4 cans as she cannot buy 3.75 cans.

<em>Here </em><em>l</em><em> refers to length, </em><em>w</em><em> refers to width, </em><em>h</em><em> refers to height.</em>
