    Answer: Solution for What is 30 percent of 3/5

    30 percent * 3.50 =

    (30:100) * 3.50 =

    (30*3.50) : 100 =

    105:100 = 1.05

    Now we have: 30 percent of 3.50 = 1.05

    Question: What is 30 percent of 3.50?

    Percentage solution with steps:

    Step 1: Our output value is 3.50.

    Step 2: We represent the unknown value with $x$x .

    Step 3: From step 1 above,$3.50=100/%$3.50=100% .

    Step 4: Similarly, $x=30/%$x=30% .

    Step 5: This results in a pair of simple equations:

    $3.50=100/% (1) $3.50=100% (1) .

    $x=30/% (2) $x=30% (2) .

    Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both

    equations have the same unit (%); we have

    $/frac{3.50}{x}=/frac{100/%}{30/%}$

    3.50

    x =

    100%

    30%

    Step 7: Again, the reciprocal of both sides gives

    $/frac{x}{3.50}=/frac{30}{100}$

    x

    3.50 =

    30

    100

    $/Rightarrow x=1.05$⇒x=1.05

    Therefore, $30/%$30% of $3.50$3.50 is $1.05$

    Answer: 2

    Explanation:

    30% 0f that number works out to be 3/5

    30/100 * x = 3/5

    isolate x by multiplying on both sides by 100/30

    100/30 * 30/100 * x = 100/30 * 3/5

    x = 20/10 = 2

    Treat it as direct proportion

    3/5 = 0.6

    so,

    x/100 = 0.6/30

    x = 100*0.6/30

    x = 2
