it's complement, namely the probability of not ordering bread, is just 1 - 2/9, namely 7/9, or about 0.78 or about 78%.

alukav5142 [94]

Answer:

$110, $44

Step-by-step explanation:

Let x = the total cost to Stefan

Jim buys for:

bicycle: $138

helmet: $16

total: $138 + $16 = $154

Jim's price of $154 is 140% of Stefan's cost, x.

154 = 140% × x

1.4x = 154

x = 110

Stefan spent $110.

Stefan's profit:

$154 - $110 = $44

Answer: $110, $44

What is 99/100 over 21 in simplest form
Likurg_2 [28]
If you divide a fraction over a number, you can just muplitply the denominator (the number under the line) by the number by which you divide:

\frac{99}{100*21}

99 and 21 are divisible by 3, so we can divide them both by it:

\frac{33}{100*7}

but that's all we can do!

so let's multiply

\frac{33}{700}

and it's its simplest form
