Tomato Bleach Spray Calculation Using 13% Bleach Originated From 8% Recipe

[andrewysk]

i got this usable recipe for tomato spray against blight.
6% chlorox of 207ml mix with 3.78l water to spray on tomato and plants that is proven to be effective.

but i have 13% chlorox only.
how to calculation this ? can someone show me detail how to do it ? my brain is rusty.

i however have from the recipe above calculated that
1ml of 100% chlorox is to 320ml water.. that's the actual chlorox to water ratio that plant can take.

how do it plug in my above 100% chlorox recipe into calculation of 13% chlorox ?

appreciate it if anybody can help.
